Wondering if anybody has run into the problem of being completely unable to active buttons, barred doors, etc. and also unable to buy/sell from NPC's. It also seems like i cant move through a conversation with any NPC either. I choose one questions, they talk about it and i cant progress any further through the conversation. Thanks for any help.

I am having the same problem with the addition of being unable to finish any quests.

This just happened to me as well, in the middle of Hag's End. I can't activate any handles or levers, see the inventory of any shopkeepers, or trade items with my companion. I hope this gets fixed soon.
