Had an odd bug in the fight against Bishop Alexander outside of Fort Joy.
During the fight, I split Bishop Alexander off away from the rest of the enemies and brought his health to 0 before killing the Hammer's Pets.
After reducing the Bishop's health low enough, he teleported off and combat ended. I then caught up to the still-alive Hammer's Pets and began another combat. For this combat, Bishop Alexander was STILL a part of it, but he was all the way across the world map where he is encountered to end the act. Every round it would pan the camera all the way across the map, (it was pitch black, I wouldn't see the area) and the Bishop would take several seconds and then use Encourage or summon a lightning cloud, even though he was way too far away from the fight to have any effect on it.
Ideally, he should not become part of combat again after teleporting away.
I do not have a save file I can upload for this one.
