Maybe this will help others who keep on crashing with god mode active. It seems to have done the trick for me but have to continue playing to be certain.
I've reinstalled every VC-Redistributable that comes with the game. Both
vcredist_x64, vcredist_x86 from
2010 and 2013.
I had them already installed so i "repaired" the installation, restarted and started the chaos campaign with the leader archaon and just godmode active.
It worked on the first settlement fight where i did crash at least more then 5 times before.
Tried that again, closed game, trainer, started the same campaign setup again and .... victory
The files can be found in the install-dir of the game under
[steam-install-dir]\steamapps\common\Total War WARHAMMER\_CommonRedist\vcredist\
Alternatively:
Right Click in Steam on TW: Warhammer -> Properties -> Local Files -> Browse Local Files
Hopefully someone who has the same problem can test this and confirm that it works *fingers crossed*
EDIT: Nevermind, again fresh chaos campaign, first settlement battle and crash after roughly 30-45 sec. Couldn't tell if spells were involved, i just let the cavalry and hounds charge into the enemy. I guess the only damage that was done at that time was missiledamage.
