Protagonist learned a lot of skills. I gave him skillpoints to test out the various skills of the game, maybe what triggered the error. But he works just fine.
Bernie prior to possessing a corpse worked just fine. I'm not sure about the skills she had though, i remember seeing mostly holy stuff wich surprised me given her supposed necromancer's background
Bernie bugged after i collected the corpse on the beach. The game showed me the message error i showed you every time i tried to have her fight from that point on. I didn't change anything about her though. So long as i pass turn instead of having Bernie fight the game doesn't have issue. It doesn't make much of a difference anyway with my MC being Lvl 18 at that point and her being low level when first entering the underworld.
