Xbox One
Companions I dismiss from the active party are spawning in the middle of every zone I enter. It started with Xoti, now its Edér, Aloth, and Pallegina. I managed to get rid of Xoti once, but the same method is not working for the three new ones.
Honestly, the bugs are sucking every last drop of enjoyment from this game. I'm sorry it didn't sell as well as you hoped, but leaving it unplayable isn't helping.
