Well. I was trying to copy a huge wall and it didn't look good. So I undid it, while it was undoing I logged out forgetting to wait. Now half of my wall is in the road and my friend's plot. If there was anyway I could fix this, I would be glad to help and/or face consequences. Thx for helping!
It's common that worldedit and voxel abilities can be used to move plots and pieces outside the region prepared for the player. If you can just provide the coordinates for your plot below, I'm sure gabizou will come along and fix it asap. I've seen it happen a few times.
