So I logged on and saw Rail was online so i went looking for his name (I had logged out in KWC) and I saw it below me. I knew where a cave that went below KWC was behind it so I went in there and dug down and saw rail mining. I blackjacked and stunlocked him from behind and killed him then recalled after grabbing his stuff. I checked what I had got and noticed i had like 6 stacks of gold ore. (video starts here) I went back and sure enough he had placed a bunch of gold ore and had been mining it.
Also I would check the chests they have in KWC as I think the gold ore might have been duped and they might have ore duped stuff.
Video will be uploaded tommorow so yeah. Got to go to sleep now.
EDIT: This morning lava and water was placed all through Ralstan. Also in the
Bale graveyard. Was probably this guy.
The problem is REALLY bad like he placed tons of lava and water which made a bunch of cobble and obsidian. If you could cuboid it away or something that would be amazing (maybe do a map rollback) (the obsidian especially)
