I know this has been a issue for a long time and I have little faith in CA to fix a game breaking bug or anything related to old abandoned Total war games. I've been having an issue of when a character has level points and I go to details to pull up their character menu. However, as soon as that character menu pops up the game auto shutdowns in the blink of an eye. If anyone knows a fix to this issue I can do it myself or a mod that settles this problem it would be greatly helpful. Otherwise, this game is actually pretty much unplayable for me cause it happens 100% of the time.

I can confirm this happens to Eight Princes campaign (when playing as Sima Ai). However, my other campaign are fine. 

When I was playing as Sima Ai, whenever a character levels up and once you get to the skill tree or character UI. It crashes. 

The only solution is to ignore the skill points. If you do not spend the skill points, it will not crash but this only happens to Eight Princes (for me at least).
