Same problem here while doing "The man who waits". Talked to Uscgrim until he teleported down the hallway and cleared the room. Went straight to Azo and confronted him in a fight. Then when I went back to the main room all the npcs were stuck in animation. An enemy attacked one of the npcs and I intervened. Then I went to the wicht room to find the door was open with the wichts standing upright with their arms outstretched (no animation). At this point I quicksaved and reloaded to see if it fixed anything. Upon return the wichts were all gone and I was hostile to everyone in the room above. Didn't see anything about a fix for this in the beta patch notes though.. Here's a copy of my save if it helps https://dl.dropboxusercontent.com/u/11970/90b96da0-fdbf-46fe-a66a-7690e4407fcd%20quicksave.savegame
