Sadly, I've had one of my characters get stuck in a wall more than once regardless of the patch version. This bug has never been fixed. However, if either you or the DK are not stuck in the wall, have them leave that level, and then magically both of your characters will appear on the other level. It beats reloading, especially if you haven't saved your game in awhile.
