Basically, I completed a solo rift, went over to talk to orek to close it out, right after I hit 'A' to talk to him, I went right over to Kadala to spend some blood. As soon as I go into the Kadala menu, the window showing XP and gold gain from the rift pops up. I close that out, and now have a "greyed" out kadala menu that cannot be closed. The control stick and xbox home button are the only things that work. The game must be forced closed and completely restarted in order to continue playing.
