I moved some furniture around in the healer's house (Theolryn, something like that), and he called the guards on me. My characters couldn't move, but the guards initiated the conversation that landed me in jail. I made the deal with devil to get out of jail, and then proceeded to the mess hall where I tried to take a tomb. The chef saw me and called the guards, and I was frozen again. But this time, when the guards ran in, they did not initiate a conversation. So, we were all just left standing there. I couldn't move or click on anything or anyone. Had to re-load the game.
