I am trying to finish the Planes of Power sig line for the first time and I am stuck on Torden, winds of change. 2 times now I have killed Yveti Stormbrood and the corpse simply disappears in the middle of the death animation. This means I cannot loot the key to open up the box. I'm running on a berserker with the inqusitor merc, she always casts Verdict to reduce Yveti to 1 hp, I plan to try tomorrow morning without that spell on. I just want to know if this is a known bug as google brought up nothing. If so, what sort of things can I do as a work-around?
