After buying the One Man Band in the Hamlet DLC, I equipped it inside. After going outside, I ran around, got a bunch of pigs following me and after going into another store, I found something bad.
The shop keep from the last store, desk and all, spawned right on the exit rug. I couldn't get past her or leave at all - even after I got her out of the desk. I ended up getting killed by a guard after trying to attack the shop keep, but that was after twenty or so minutes trying to get out normally.
Honestly it was really funny?? But after five days underground trying to get to the castle, it was a pain having to be killed and restart the world over again.
