Two benches in Thirsk Mead will cause the player to clip through the tables they're placed at when used. This results in items on the tables going everywhere. It would have made a lot more sense if the developers had used the table-bench combo instead of making them separate.
Note: This was brought up years ago and apparently never fixed (
Bug #17936). I can't see any indication from the comment in the ticket that it wasn't possible to fix, though there is no listing in the change log.
