The crash happens when I attack the bandit group with my Sovereign - there's a caster in the group and the game crashes when he starts to cast whatever he's supposed to .
I take responsibility for this crash. I missed a couple of lines of old code in the ACP mod, and one of those units is from it (the wraith). It has been fixed now, and the new version with the fix is up. I apologize, the last thing I want to do is to contribute to more crashes! You'll have to start a new game to have the change take effect. Again, sorry about that, and at least I have the solution for you.
Here's the link to download the newest version (with said fix in it):

P.S. - Other than the crash, I hope you've enjoyed it so far.
