I'm 34 turns into my AoC campaign as the Franks and having a blast. Unfortunately, after ending my turn the game stops responding at the "Gallacian Separatists'" icon.
I've gone back to previous saves to see if that would help, but the crash repeats itself without fail at about turn 33 or 34. I am submitting four crash dump files from my attempts to return to earlier savegames.
As for mods, I'm running several reskin packs that should have no bearing on the campaign. However, I am also running a Theme of Sicily unlocker. It cannot be disabled, or the save will not load. I'm not sure if the mod is causing this or not, however, I have seen many other users with similar issues regarding crashes at AI separatist faction turns, so I thought it would be worth a shot to post this info.
