Hi, before I start I'd like to say thanks for any help you can provide. I've been running a server for a couple of months. I'm using Towny and there's a problem when someone unclaimes a town block. I have changed usingPlotManagementRevert to false but it keeps happening and even if I //regen them with WorldEdit, it keeps regenerating in a wrong way. There are like big holes in the zone that go down to bedrock, and some sort of "colums" with bedrock or lava on the top layers. I have disabled Towny and now it doesn't happen, and as I need to use Towny I don't know how to fix this. The bukkit version is 1.2.4-R1.0-b2126 and the Towny's 0.79.1.0 Thanks for any help and sorry for my english!
