I can't talk to Barbatos in the Alchemy Tower.
He's standing in front of the Alchemy table like he is mixing a potion, but the option to talk to doesn't pop up any more.
It doesn't time out either... I think I might have assigned him to make a Extra Strength Potion and teleported out back to a previous location or something, before he finished mixing the potion. When I went back, I haven't been able to talk to him since.
