Thrall "Follow" Permanently Disabled on Character

I asked a thrall to “follow” me and it worked fine. One occasion, I was unable to ask it to stop following me because it was in the way of some furniture so it gave me an error message.

I logged off to take care of something, then logged back on. My thrall was still there, only now it isn’t following me anymore.

I asked it to follow, but now it says a thrall is already following me! The game permanently disabled thrall following for my character on an official server now.

I have tried asking other thralls to follow me, but the game keeps saying a thrall is already following me when there aren’t any.

Please patch this!
