Playing as Sweboz I have found a couple of things that may be problems.
I have taken Gawjam-Kimbroz, Gawjam-Rugoz and Gawjam-Skandzawaroz.
When I go to que up a govt building, there is no level 2 as a choice, only level one, three and four.

Also, when fighting the battles to take these towns I get CTD when the enemy general is killed. I have restarted three different times and I get the same thing each time.

If I auto resolve the battles there is no crash. If I make the enemy route without killing the general, I can chose end battle and there is no crash.

Could this be related to traits of the enemy generals? Or is it possible that it is related to the white banners that the rebels in this area have? In .72 they did not have white banners. What was changed that gives them white banners?
