Re, I'm playing on an asus laptop : - core i7-4700HQ @ 2.40GHz - 4 Go RAM - GeForce GT 740M I've done some more test an I really don't understand... As I was stuck, I've choose to play another map (the outpost, a quick one, no problem, no crash) and after that I come back to "TD3 heart of lone salvation" and as my savegames where still bugged, I have restart the whole fm on easiest difficulty just to try ending it once (and quickly). And I got the bug again ! But this time, he don't come with keys, but with maps or lockpicks ! So it's not a key bug... More an inventory one... But witch was ever more disturbing, is the fact that I got two quick saves, the first one before I have lockpick a chest, and the second, right after. So when the game have crash, I've test the first savegame, thinking she must be good as I've use my lockpicks just after this moment... And she is bugged too . It have make me feels that the bug have corrupted some fm's relative file. So I have uninstall the fm, backup my savegames folder, clean the fm with the TDM menu, reinstall the fm, start a fresh game and test if I was able to pick / use my locpicks and maps, everything was ok ! So I have restored my savegames folder again, load my first savegame (the one before I open the chest) and the game crash again when I took my lockpicks !!! Is there a way to get game logs or anything which could help ? I can upload my savegames too if someone want to try reproducing the crash... ++
