Loki battle crash
 

Is anyone else having problems with this battle? I've tried it 4-5 times now and it crashes every time.

EDIT: Finally managed to defeat him, I randomly experimented with different setups and was successful when I took only 3 out my 5 stacks into battle (?). I noticed that at least part of the reason for crashing was that fire effect he places on your troops and trying to move to another cell (I had shooters only).
