Normally I don't ressurect a threat like that, but ...
I build a Great Hall yesterday. Whenever I walk out using the left door I end up inside the Great Hall slightly off center. From there I can wal out the back or left. If I click towards the right side it will push me out the left side. I think this could be be abused to get behind the world boarder, so I wanted to report it beforethe new world starts, even if it adds to your work 'til then.
PS: I attached a screenshot here. the square inside the great hall is me. (This works whever I ride a horse or not.)
