This has been happening to me in all battles for at least 2 weeks now. After the dwarf patch I think. Mulitple posts. Multiple support tickets. Nothing back yet except the auto reply.

Damn. That sucks. Good to know. It was my first time having the crash, and a quick (I think I scanned around 30 posts) perusal didn't reveal the issue. 

Thanks for the heads up. 

Same here. Clan boss crashes after a minute into the battle. No support help. I keep losing keys with no compensation, no help, no fixes. This is very frustrating. I will not give this game a single dollar until it is fixed and if not soon, I will quit playing. 

I just had the same issue 2 times in the same week. Very frustrating. If it wasn't for the clan keys it wouldn't be so bad, but it discourages me from wanting to play.
