I saw two characters get stuck when trying to enter a cave. The character would appear on top of the hill and was unable to come down. It happened at the entrance to the Barrow Downs crypt and also at the first Angmar dungeon. Both are the same cave tile, maybe that has something to do with it, I don't know.
Also my character is an alcoholic elf, and so far no store or tavern sells any wine. I be you never expected someone would have a problem with this...heh...I hope this information helps somehow.
