[B20] CRASH: Game tried to walk the dead golem?

[Canderel]

I was kinda clicking on the party members, because you can switch, but it seems that it makes time elapse.

So I clicked my character, then the golem, then I clicked my character again and then:

[LOG] Leoric hits golem (servant of Leoric) for #LIGHT_RED#15.93 fire damage#LAST#.
[LOG] #{bold}#Leoric killed golem (servant of Leoric)!#{normal}#
[LOG] #MOCCASIN#Character control switched to Leoric.
