I left clicked in the middle of Esmerelda's shop to walk there from the eastern edge of town and my characters walked right through 2 of Esmerelda's locked doors instead of entering in the front. The doors remained locked afterward.
Yeah this is caused by the door not rendering at a distance and so it seems as if the way is open. Also your lead character will run the straightest way there, running through solid objects. If you take your party upstairs (or downstairs) at the Inn or the Mayor's then you will be able to free your stuck character.
