Here are more details as I promised: I've updated darkmod, some little files were downloaded, but I supposed only CRC files, next I started my tests. The failure message always is: Joint 'HIPS' not found for attachment position 'HIPS_SHEATH_L' for entity 'XXX' - where XXX is always some different name of some entity in the map definition. There are two kinds of behaviours: A ) - mission falls off to the difficulty/objectives screen without any message, there is no difficulty choosed, and objectives sheet is empty, you can choose difficulty again and click start mission again, loading starts again, falls of again to the same screen but message box with error description is shown. You can choose start mission again and again and every time the message box with same description will be shown. So the message is not shown only first time. This kind of behaviour is in the missions when animated description of plot is shown before objectives screen like alchemist or beleaguered fence. Additionally - I can't tell if it is normal or no - I can't skip the animation - when I press escape DarkMod's main menu is shown and next escapes do not take me back to the animation - I need to start mission again. B ) - mission falls off to objectives screen or rarely (once or twice) to menu, messagebox behaves like before, but sound is disabled. I can start mission over and over again with same effect - joint hips error and no sound. From my experience this happens when missions have plot displayed the same way as the objectives - on the sheet of yellow crumpled paper. After restarting DarkMod sound is OK. There are deviations from both A and B behaviours sometimes described below. It also seems that optional presence of buy screen (some missions have it, others do not) does not influence the behaviour. Often next tries of loading once installed mission make the progress bar go slightly further but it's only true for first 1-3 attempts. Then mission loads or always fails at the same level of progress bar. Here is the mission list with additional details if some occur: 01) alchemist - no, behaviour A plus after escaping the animation cursor is not visible but I can move the mouse and highlight menu positions if I'm lucky and click them then or cursor is not visible and I cannot find any position like cursor is not moving virtually anymore, but this happens only after load failure. When I escape plot animation before first failure occurs cursor works fine. Entity name is Pertti. 02) awaiting the storm - no, behaviour B 03) beleaguered fence - no, behaviour A 04) betrayal - (this is the mission with prison and skeleton) - yes, but behaviour A - how this is possible? Mission loads successfully after second, third or rarely fourth time - never first. Previous behaviour is the A-kind, messagebox is not shown only the first time. Saving works. Loading the save works always the second time, first time messagebox is not shown as always. 05) builder's influence - this is interesting. First try - behaviour B, although there is animated intro in that mission. Second time - full success and sound comes back after loading when 3d mode is on (when plot animates and objectives/buy screens are displayed there is no sound). I can switch to menu and back and sound is fine everywhere. Mission looks beautiful, mmmm!!!! Saving and loading works great, no need for additional attempts when loading the save. Another try - escaping animation of plot and again I can't go back to it - I need to start mission again. I do it waiting whole animation to end every time and mission loads after second attempt as before. 06) business as usual - no, behaviour B, tried about 10 times because second time was interesting - game loaded completely, 'game loaded - please wait' label was displayed, few seconds of waiting like in every missions that reached this point and instead of mission I got objectives screen with hips error message. This never happened again. 07) caduceus of st. alban (mission with beautiful lamp with planets around the bulb:)) - exactly like builder's influence, but this mission has no animated plot - I come the reasonable idea that existance of plot animation in the mission has really nothing to do here (unlike I thought before). OK, let's go to next mission. 08) chalice of kings - like 5 and 7 09) crown of penitence - like 5 10) entertainment - like 5 11) flakebridge monastery - like 7 12) glenham tower - like 7 13) heart of lone salvation - mission has animated plot intro and is unusual - first attempt fails to objective screen as always after displaying the plot during loading, every next attempt of starting the mission by clicking 'start mission' button on objectives screen loading finishes and game escapes to objectives screen with joint hips error on entity 'andrew' - I remembered the easy name. Also interesting - in every next attempt since second I do not need to watch animated intro, I've got objectives screen instantly. Of course when I go to main menu and start mission I need to watch intro again - but only first time. Also next - when game fails to objectives screen names of difficulty levels are corrupted - they look like constants in the code or some configuration file, not like content of this constants. Something tells me this might be good mission for testing.... Finally I press escape and instead of displaying DarkMod menu I got intro again. I press escape again and have menu with no cursor. I use ctrl-alt-delete and first time I have no cursor in windows also - to be more specific windows task menager is not over the desktop but over darkmod screen and I suppose this is the cause for which cursor is still not available. I need to use keyboard shortcuts to kill darkmod in task manager. 14) illusionist tower - like 7 15) kinghton manor - no animated intro in this mission, this mission has plot displayed with interactive buttons to display next, previous screens of plot or skip it. Behaviour B. Entity name is 'Female_servatnt1'. No other bugs like in mission 13 so try looking into 'Female_servant1' definition and testing on this mission. 16) living expenses - behaviour B, entity is complex but contains word 'nobleman' 17) lockdown part 1 - started on the first attempt and starts every time easily!!!!!!! But there is other little problem, it has empty plot screen, but you can click next and difficulty screen and all after it is OK 18) mad's mountain - first attempt fails without messagebox, no sound then. Every next attempt causes message box but for the first time error is different but error message might be very usefull because it defines C++ class and method that failed: idAFEntity_BASE::LoadAF: Couldn't load at file 'GUARD_BASE_NEWSKEL' on entity 'ADTM_ENV_RAGDOLL_BEGGAR_1' 19) mandrasola - like 15, of course different entity name 20) NHAT mission 1/3 - First after restarting DarkMod after installing mission the great thing is changed main menu theme. Second is the movie, wow! but sometimes pixels in this movie are corrupted. Next the animated intro, difficulty screen, I click start mission and after 1/4 of progress bar it returns to difficulty screen. I click start mission again, loading starts from the point it ended (!) and mission works great starting from another animation and then I can play(save/load too). I can only suppose next two missions work the same way but to check this must finish first mission. 21) outpost - first time failure without message box, second time loads successfully. This is example of mission that fails to main menu, so you need to start it over, watch the animated intro again and again as many times as it fails. Despite of starting mission over loading starts from when it ended before - that is odd. 22) pandoras'box - behaviour B except two things: fails to main menu after first attempt (luckily no animated intro is here, so second attempt is fast) and voila - second attempt is successfull. It seems that disabled sound after first attempt is a good sign. 23) parcel - don't praise the day before the evening - disabled sound after first attempt, going back to main menu, then always joint hips error on entity 'jack'. 24) patently dangerous - like 23, entity 'Oswald'. 25) return to the city - like 15 and 19 (the same interactive plot screen) except that at second attempt everything works fine 26) rift - first attempt failure with no message, second attempt joint hips error on something like 'ADTM_something_GUARD_1'. I've seen this entity before in other mission with joint hips error so it's worth mentioning, but I can't remember which mission that was. Also it's worth to notice that instead of loading screen there is standard DarkMod theme with clock displayed - the same like when the DarkMod starts. This maybe some problem indicator or also it may be this way in this mission. 27) somewhere above the city 1.1 - very long intro but fortunately on first attempt mission fails to objective screen and second attempt is successfull 28) sons of baltona part 1 - no intro, first attempt fails, no sound, second attempt successfull from where loading finished on first attempt 29) sound alert and blackjack trainer - no objectives (funny and loading screen is theme with clock as in 26 (so I suppose this is the way it should be). First attempt fails to objectives screen, second attempt join hips error. 30) special delivery - first attempt fails to main menu, no sound, second attempt successfull 31) st. albans cathedral - first attempt fails to objectives menu, every next gives message box with join hips error on entity ADTM_AI_CITYWATCH_1 32) swing (mission with swinging something) - first attempt, full success 33) tears of st. lucia - first attempt fails to main menu, I haven't tried second because of very long intro, but as I remember from yesterday it's joint hips error 34) thieve's den - first attempt fails to objectives screen, no sound, no objectives displayed, you need to choose difficulty again and start mission again and got joint hips error on ADTM_AI_CITYWATCH_1 entity at every next attempt 35) thieves - first attemt fails to main menu, intro must be watched again when starting over and there it is: joint hips error on ADTM_AI_CITYWATCH_1 entity, probably st.lucia has the same entity as I remember 36) too late - first attempt fails to main menu, starting over (no intro) brings success 37) training mission - surprise, first attempt fails to objectives screen, no sound, second attempt successfull. Identical mission before was in french language, I don't remember which one 38) transaction - first attempt brings you to main menu, no sound, starting over returns message box with joint hips error on entity CITY_WATCH_STREET_PATROL_ALPHA 39) trapped - first attempt brings you to main menu, no sound, starting over successfull Don't you think that if so many missions fail because of joint 'hips' error than it isn't rather a problem with missions themselves but a common problem inside the engine? Responding to some other advise I'll try downloading all content tomorrow, now I must go asleep. I'm attaching list of files in "C:\Program Files (x86)\DOOM 3" directory - I haven't found any suitable tool for this task so I wrote one myself - I hope output is easily readable. I've attached my tool so you can generate your own result and compare them in kdiff3 or some other editor with compare option. You use it by entering the desired diretory in command line and call java -jar C:\dirscan.jar [--md5]. Parameter is optional. Ofcourse dirscan.jar in this example is placed in C:\. dirscan.jar will fail if scans the directory where is placed but I have no time to fix it now. Output is properly idented on linux, I can't now find reason why indent is not correct on windows, but should be readable. I hope my hard work will pay off and serve you well - I worked almost 6 hours on it instead of helping my girlfried tidying up our apartment but she understood so don't worry ;P.
