Missing house???

Well... I logged in to the server, climbed out of my mine, and found that 90% of my house was missing. Here are some pictures of what's left. The coordinates are also in the images. (they may not fit on the screen, try opening them in a new tab)
As you can see in the second image, there is a field behind what's left of the structure, and that used to have walls and rooms built in it (I had no roofs yet). Please help!

hmm i see piggy ill look in to it when i get the chanes failing that il get one of the admin/mods to do so

the griefer was a player named shadow9712 and your house has been restored. Artakha out.
