Hello, I don't belong to this town and I have no idea what this town is. I went north up to -8939x -3066z 64y and found a completely destroyed town, floating chests and I did a bunch of /seen commands and it seems like it could have happened yesterday. Screenshots: Spoiler I didn't have a piece of string with me so I don't know if that area is a legit region but it looks like it could have been becoming a town and got attacked. I have no idea what this place is, I just know it's been destroyed.
The first thing you should do, is walk into the area and see if a region comes up in your chat box, if it does, then its a town, if not, its just random wild grief .
I saw this as well when I was on my way to find a spot to put my town, I knew it was in the wild though, but I was shocked at the amount of damage.
