Arran the dwarf in undertavern is bugged to where I cant speak to him with any of my characters. I click on him to talk to him and it pops up the speech window then immediately closes it, even loading to some previous saves where I was able to talk to him doesnt help. No other NPC has this problem, and if I attack him or pickpocket him he speaks to me just fine, and then attacks me, but even after that I still cant talk to him normally.
