When moving out of a map, like the Jammer Caverns or a Mage's Guild, you can end up displaced onto a tile adjacent to the exit of it. Seems to happen without fail if moving from say, the F5 shortcut to outside, resulting in you getting thrown into the eastern sea tile by the cave.

The above example happens if you only barely leave the first floor of the cave, leaving you on the top pixel or so of the Jammer Cavern. Then you can walk out into the ocean, or walk back down onto the correct tile.
