In your preference file.

You probably want to remove your descr_campaign_db.xml completely (i.e. let it load from the pack) and see if it still crashes during the AI turn.
Also, can you list which other files you have modded currently (and active during the CTD)

Okay, here's the new errorlog, this was after removing the descr_campaign_db from my mod folder:

Spoiler Alert, click show to read:

as for other modded files:
-export_descr_character_traits.txt
-descr_character_traits.txt
-the preference file, (Mikemod.cfg) to make the error log, disable intro movies and unlock the other factions
-and a bunch of files to add a new faction which I couldn't get to work, so I just got rid of the data/worlds/maps from my mod folder.

[FactionHeir]

Traits file in unlikely to cause a CTD in a running game. If it causes one, then at game startup, as the file is only loaded then and otherwise read from memory.
Intro movies shouldn't cause a problem, although I haven't tested that, so can't say for sure. I usually just change it in the pref file.

What's descr_character_traits.txt though? (the non export one) I can't remember seeing that when unpacking.

So all in all, what you have modded right now (i.e. the only files present in your mod folder other than the required files to make a mod folder work) are:
EDC
DC (whatever that is)
descr_strat

and outside you got the preference file.

Right?

[GeneralMikeIII]

11:13:48.687 [data.xml.tag] [error] File:[MikeMod/data/descr_movies.xml]Error: empty tag.(4:26)
11:13:48.703 [data.xml.tag] [error] File:[MikeMod/data/descr_movies_tracks.xml]Error: empty tag.(6:20)

The weird thing is, the files that show up in the errorlog aren't even ones I've done anything to

DC (whatever that is)
descr_strat

Oops, that should just be descr_character.txt, the file that deals with characters on the campaign map. All I did there was add some movement points the the agents, and lower the upkeep for some of them.

And I got rid of the changes I made to my descr_strat, but there are a bunch of other files I modded when I was attempting to add my faction, like the files for the flags and stuff, but none of that should have an impact in-game, should it? Plus iirc I was getting this error sometimes before I tried to add my new faction.

EDIT: just went through and removed the files from my mod folder for the new faction, CTD still happens on Milan's turn.

[FactionHeir]

Did you do any modding the first time you experienced the AI turn crash?
In my experience, it only happens if you mod something and did something wrong.

While I wouldn't think extra MPs would cause a crash, I suppose it can be possible if there is a max somewhere which wasn't properly capped and added movement boni forced it to overflow.

As for the other modded files, it would be good to have a full list - one of them will likely also be the culprit in the error you get shown.

Best would be to remove all files from your mod folder, see if you get an error / crash at all.
Then add one file at a time, beginning with the file you are most certain about etc till you find which file causes a problem.

[GeneralMikeIII]

I don't have time now to go through all the files one-by-one, but I was able to copy the save file for my campaign from my mod over to the vanilla game and load it, and it still had the same error at the same time.

Note: This was a few turns into the game (turn 8 I think), so I don't think it is a mp problem, because then shouldn't it have triggered on the first turn (when the modded file would first take effect)? Like on the first turn, I was able to move my spy for all of his mp, without a crash.

[FactionHeir]

If there is a crash at the same point and time, its likely the save is I think corrupted. You can test this by doing something else before the crash and seeing if it still does, like attacking some Milanese unit.

Its also possible that a file that is only read for new campaigns was modded incorrectly resulting in this behavior, that in vanilla it also still crashes.

Really, the only way you can find the culprit is as I outlined before.
