Rolling back while on boat can respawn player at Postern

This had happened to me, but I had slightly more devastating effects. Both players were out on a boat parked at the pirate monkey island. Rolled back, and both players appeared at the portal. However, the terrain was disfigured and there were parts of land completely or partially removed and replaced with water or other terrain. In some areas where there was terrain, I was unable to walk to them. Other areas where the terrain was replaced with water, I still could not walk, but there were trees, pig houses, mushrooms or saplings on the water.

This may have been fixed in the Maxwell update (2.59) but it would only apply to saves/rollbacks that have been made since the update. Let me know if it's still happening and you're certain that you're rolling back to a save that happened after the update.
