Again, I doubt something like that can CTD the game in the middle of a loading screen, but backup and try restoring the original traits and ancillaries.

If that works I'll be a very wrong person very happy :).
Unfortunately that isn't quite true, all conditions come from the engine (we have no ability to add new conditions), but there are some conditions that are known to cause CTDs in reinforcement battles (NumEnemiesInBattle is one).
