Possibly no griefers?

I've been looking around and i am finding blocks missing from the server which is odd. I check the map and the area with missing blocks is mostly protected. I have a feeling that blocks are being replaced back to old data as i have laid some dirt down and now is gone. I have placed blocks down on my old creations such as glass and it has turned back to dirt.
Please post here and see if there has been anything like this happen to you. This i think could be the server not able to memorize the blocks placed or maybe a virus. The damage is too much for a griefer.

I suggest to everyone to stop building massive projects and wait and see the problem to this situation.

As the rest of the forum says. It was a rollback on a player. No grief
