It's been awhile since I've played this mod, but I decided last night to start a Chaos campaign, something I hadn't tried since the first time the campaign map was released. Upon my first field battle, the game crashed less than halfway through the loading screen between the map and battle, and I was given a non-specific error message stating that Rome: Total War encountered a problem and needed to close. After searching here, I discovered and fixed the texture error for the Chaos Marauder Horsemen unit. Hoping that was the solution, I attempted to load that battle again, to no avail. I checked for the problem in all my other campaigns, but all those battles worked just fine. After some trial and error, I finally discovered that the game only crashed when sending any of my Chaos generals into combat. Thinking it may have been a problem with the unit (Chaos Knights), I tried using them in a custom battle and encountered no problems. So I think it might be a problem with the named generals themselves. I'll try a few other things when I get home from work, and I'll update here if I manage to solve it. Sorry for the wall of text, but I thought it best to go into as much detail as possible.
TLDR: Attempting to launch a battle from the campaign map with a named Chaos general causes the game to crash partway through the loading screen, and I haven't yet managed to find a solution.
