Haven't been able to replicate it, but I THINK it was because I changed maps and was immediately attacked by a harpy, like the changing of the map plus the battle glitched it.
Found out that if you are anything, 17 (like -3,17) and go south it immediately puts you back at the entrance to the map, 20 there's no X,18.also found a cave that had zilch in it, like you plan on putting something there eventually.
