Hey Pat, I just made a post on the ROF forum, I encountered a Gotha bomber in a Dolphin mission with PWCG and for whatever reason the gotha tried to maneuver like a fighter. Someone replied and said that maybe it could have something to do with the mission parameters you had set for the AI gotha to perform?
It may not have anything to do with PWCG but maybe it's worth exploring, I've also seen Two seaters try to maneuver like a scout and I've only ever seen it happen in PWCG missions so maybe the way you've setup some of the missions is affecting that.
