Found the lava around my fort missing a few days ago.Today when i logged in i found my entire hallway flooded with lava source blocks.Below are pictures of my fort with lava(that is gone now).And the hallway before and how i found it today(i placed the random blocks to remove the lava but somebody clearly placed it.I thought that nobody can alter the blocks in your claimed land unles they claim it themselves.)[attachment=6:2011-07-16_00.18.41.png]
