My home was griefed recently. Diamond blocks, wart farm, lapiz blocks, an iron block were taken. Which is strange about the diamond because there was a sponge in that area but is missing.  Also it appears that my sponges are missing aswell. Had a sponge at my warp location so nobody could enter home. There also should have been a sponge at the surface entrance. And my pig is gone from his home. And my few iron golems are missing.
