Alloc you know your rlp command for removing claim blocks/keystones
Could the same trick work for other blocks, I realize they would not have an owner in the same way but If a range was give could it remove the blocks, Directly in this case water,
A griefing trick people do if they put water down up high and let it run down and get all over the place very very hard to clean up,
I dont know how often other admins have this issue but I've had it a few times, sometimes its easier to regen that region
