someon has any idea what happend could a admin do a roleback?

There were some crops that popped up, but then you started whining when I teleported you to them so you could pick them up... nothing more on the logs, so nothing more I can do. Either way I'm not sure how anyone could get up there considering it's floating 200 blocks in the sky.
