Saves don't load!

[wesp5]

So while beta-testing a mission I made some adjustments to def and script files for my patch, only now the saves made earlier won't load anymore and the game freezes. Is there a solution for this, like getting the game to load them even if errors are caused by the mismatched files?

Perhaps you have a infinite loop in one of your scrips? Infinite loops can cause freezes. But I also thought the script parser was able to caught those?

Btw I don't remember ever having, Doom 3 in this case, freeze because of changing a def file (or even a script?), the worse it could happen is crash the game or cause ingame bugs but I'm not absolutely sure on this.

What do the logs say?

Revert scripts to their original state.
Script mismatch immediately make savegames incompatible.

Ah, I guessed as much and already tried to revert the scripts to the last patch. Sadly it seems as if I made a manual change before playing the mission which is now lost and I can't remember what it was! The logs say nothing and it can't be a loop because if I start the mission from scratch everything works fine...

Another thing to keep in mind is that def file properties are embedded in the save file, so a mission restart is required for def changes to take effect.

If you aren't doing this already, you might want to consider keeping your TDM directory under version control. I use Git for config, def, script, gui, and other plain-text files. I also commit overridden textures, but otherwise I don't commit executable, pk4, or other binary files.

You can go to idProgram::Restore, delete "saved_checksum != checksum" check, build the code and try again.
But it is quite dangerous.

The savefile does not store your scripts, it only stores their hash.

Does the hash file include the date or only the content of the file?

As far as I see, it uses the bytecode + file indices and line numbers.
