@Lexx If this is something you've planned to work this way than know that the bug of loosing perk window when switching characters in ControlCombat=2 can be bad luck and doesn't have to involve perk banking. Simply put one ends combat by another bug (like the look at Vault Dweller (dude) when controlling an party npc) and there are still enemies around. Let's suppose Player get's a level with perk after that buggy combat end, but there are still enemies around, so the combat starts anew. you kill stuff with pc and npcs and all of a sudden a the end of the combat you loose perk window for a legitimate perk. That's what i call either a bug or shitty game design. ( if it was intended ofcourse ).
