Lost entire chest of items

Yesterday the server must have freaked out a bit while I was moving. I transferred ~800 iron ingots, 64 gold, and misc amounts of redstone, wood, ladders, saplings, coal, etc. to a new location further from the spawn city hoping I wouldn't be griefed so much on a new project.

Anyway, the server saved the changes made to my old storage location but reverted the whole area of the new storage location to a time before I ever arrived! My new chest, the area I put it in, and the sign marking it all gone. If this was just a bunch of stone or something I wouldn't mind, but I lost a significant percentage of the iron on the map and it would take days or weeks to replace it

I'm not a donor yet, but if an admin could check into the matter I'd really appreciate it so i can have the iron needed to make a nice long rail track once I get the tunnels zoned in the future.

Assuming your in-game name is TunnelBorer I'll try to catch you online sometime tonight.

Thanks, and sorry, my in-game name isn't TunnelBorer (yet). It's AlanDominique
I was waiting for inspiration to get a nickname, TunnelBorer seems to work OK, I have to modify my chest locks though before changing.
