i just want to say that if you decide to set 'use at your own risk' for the blacraft server; i hope you'll the items i lost in a recent server restart thing.
I was working on a automatic volcano creator, and after i'd finished, i mined away the few layers of cobble from the test run and was building a small town to bury under the volcano. I put all my stuff in a chest in a house because i wanted to go back to desrertopia and fill my inventory with cobblestone to build with. then the server had a 'server restarting, you will be kicked' message, and then i relogged. when i got back in, the server had rolled back so the cobblestone i had mined away had replaced my chest and my items were gone.
i lost:
diamond pickaxe, 98%
diamond shovel x2 : 100%
bow x 1
redstone x 32
torches x 32
bread x 64
flitn and steel x 1
bucket x 6
exp required to enchant the stuff i lost = 471 bottles of exp
also last time from the library i built, i forgot to request these items it took to build, because i was more concerend about my diamond armor which was worth significantly more:
netherbrick: 12 stacks
blue wool: 2 stacks
red wool: 2 stacks
wood: 144 (1.5 stacks)
