Oof. I just went to check it out myself and saw the signs.
Well, I hope we can get it sorted. It's a thing of beauty.
That said, I did use /back *once" last week to regain my sword after I fell into a chasm and got swamped by zombies, but this was N of 'topia. Could that have caused the glitch? It's the one and only time I've ever used that command in the new world, so I hope that didn't fuck things up.
