I just had a ctd, don't see any reasons as you mention. When i done my turn in war with AI, thier city attacks my unit and ctd happens.
I don't know how to give you some clue like log, maybe you show me way to record log to make these bug clearly.
And here my CTD save, just end turn and game will crash. Hope it can help.

Thank you for your work.
EDIT #1: Sorry, i forgot to tell you what mod i use. They're your recommended DLL, SP mods, Addict Info, More greatworks, Quick turns, Giant Earth maps, IGE.
EDIT #2: I forgot to tell you there's one mod i use that's R.E.D modpacks and i think it has to do something with the CTD. I disable it and i can advance to next turn but now mysave is corrupted even i load another save with 5 turns less. Any solution that fix this corrupted save? Please tell me! Thank you.
