About the crash i know nothing about it, about the "berserk" it happened to me too, but with phodom(and fradz) too.
Oh, and i think "deathless puzzle" is buged, you know, there's still two deathless alive and their colors don't match, so it doesn't matter how many times you kill them, they won't die.
PS: Aero REALLY should take out the money that the "deathlesses" give, cause it's a infinite amount of fast money(or at least put little money, so it'll be a infinit amount of slow money)
