What on earth happened to my house

Well as most of you know, gambit copied and pasted my house because i was moving. Everything was fine went i went to bed last night, but something happened when the server updated to 1.1. I cant even explain what happened so here are some pictures:




I fell in to this when i was walking out of my house and was ambushed by mobs and died. I lost a set of diamond tools to what ever this is.

this isnt good.... hoow far is does that carvern go? this looks like some selcected a region they probly didnt mean to then did replace stone with air.. if u look close thats all thats missing ant seems to be in a straight line

Uh, I talked to mined and I think you can just world edit my castle away. It just seems too out of place. Also, with the underground I would reccomend //regen to make sure there is messed up gravel or anything. A lot of gravel fell to the bottom. I will talk to you on mumble later.

k ill take care of it make sure no one else messes with it, btw /regen can be very dangeous ill talk to u on mumble later we will get it worked out

Bobster also had this happen to him.
