Well just got a total freeze of the game when arriving in Brinnlaw, spellhold's island. I traced this to this mod, uninstalling fixes it. By chance it was one of the last things I installed, so it shouldn't break anything in my save, at least nothing major. I had installed this speicifcally to be able to send the party member who is replaced by Imoen back... it was for role play reasons only, I'll do without it. So be careful if installing this in a modern ee game then.
