Help - Some kind of (TP) error

[Granaten]

Hello. I am running a Tekkit Classic Server.

Yesterday were all fine but today some of my players are complaining about a problem. It's like when they walk they somehow got "Teleported" back. Or when they are building and are over the ground they got "pushed" down. If he e.g. jumps about 2-3 blocks down in his house, he got teleported to the top.(Roof)

One of my players find this and said it could be the problem:

[WARNING] Received a TileEntityData packet for a location that did not have a TileEntity: (656, 44, -1171) 1: 51, 0, 0

I haven't added any new plugins just before the error came up.

Plugins:

Essentials

Essentials Group Manager

Votifier

Autosaver

Backup

Buycraft

Betterbroadcast

PluginMetrics

WorldEdit

WorldGuard

ChestShop

CoreProtect

Tekkitrestrict

Hope some can help me really fast!
