Ok so I am in the theives guild. Everytime I get assigned a new fence and I go there to sell my stuff to them, the barter tab isnt even an option. Ive just been assigned Fathis Ules and I have to fence to him 1000 gold. I went to his house and he even said i could sell my stuff to him, but I couldnt barter. That also happened with the lady fence 2 fences before Fathis. I eventually got to barter with the lady, but I cant barter with Fathis Ules still. Is there something I have to do?
