I am experiencing a reproducible crash in tactical battles. I'm playing as Pariden, and cast Shrink on an Umberdroth after the battle begins. Everything is fine up to the point where the Umberdroth dies. At that point, the program doesn't seem to realize that the tactical combat is over. The combat does not end, and I am unable to take any further actions. As you can see in this screen shot, the Umberdroth is still in the action list on the left side of the screen, with 0 hit points. The square where the Umberdroth used to be, fighting my characters, is empty:

Clicking on the button in the very lower right corner of the screen to Auto Resolve the combat causes an immediate program crash. You can get the debug.err file here.
For some reason, no .zip file is produced contained a program dump. But the good news is that this issue can be reproduced easily using my save game file. I tried it 3 times in a row to make sure, and all 3 times the same crash happened. So get the save file here.
When you start the save game, the Umberdroth immediately attacks and the battle starts. Simply cast Shrink on the Umberdroth and kill it to cause the bug to happen. If the Umberdroth resists the Shrink, keep casting it until it succeeds. One other strange thing I noticed is that my characters' health bars stay full even when taking damage. So there's actually 2 bugs happening here.
