Today I tried to attack a temple and it crashed every time. My team was spectral/healer/wee witch, spikey and moondrake. Crashed two times as soon as only 2 shark minions were left to kill. I replaced spikey with crimson witch and managed to finish the battle by killing the shark minions before the titan. I think the bug is related to spectral's possession skill, rather than spikey, because I noticed that the possessed shark did not turn on the other shark and it was still attacking my team. Might be a bug that happens only when 2 sharks are present, because I successfully possesed sharks that turned on the other minions, but not against another shark.
