This may be related. I'm reporting it here, since my in-game bor reporting doesnt work.
The game crashed 3 times on me today. First, when attacking the first set in the first line of crypt, the game kicked me out just aftrer the fight started.
Second, when attacking in a guildmates temple, same thing. I started the attack, got kicked out pf the game.
Third, on the final tower of level 28 normal campaign, again, got kicked out of the game, just after starting the fight.
The first two cost me the fights. The normal campaign one restarted ok, and nothing was lost.
Sorry to report this here, but the in-game bug hasnt worked for me for manths. And I.have had others reoport that, for me.
