This is the scene where this happens. I guess it's scene design related issue... It's in Diantogmail village. It's a very difficult terrain though.. however also very niceMy surgeon companion just perma-died because of the bug of custom formations. My companions were assigned to formation VII.
With 164 elite units I was just performing "cleaning" job and attacked 52 enemy party (mostly pheasants - no chance to kill anyone in my party).
Due to the bug my companions were transported immediately next to the enemy party (far away from my party) and got killed.
My surgeon died permanently.
I thought this issue was already fixed!? This is not funny anymore...
