You have 3 options:

1: Update Dimensional Anchors manually, the newer versions of Dimensional Anchors will fix this problem.

2: Update to one of the newer dev versions of tekkit lite (0.5.3 fixes this issue)

3: Delete the Dimensional Anchors jar file from the mods folder on your server, this will however disable all chunk loaders on your server.

Personally I recommend step 1, but before you do any of this make sure to back up your world.

[greenfox]

I deleted Dim Anch because I can't ask my users to manual update their clients. Now we're on 0.5.7 and it works just fine.

[greenfox]

now I"m having a different problem though. Now occasionally when I enter a new Mystcraft world, it crashes the server and recrashes it everytime the stuck player logs back in. The only solution I've found was to delete the /world/player/player.dat file for everyone in that world.

That's fine, but I just want to recover those inventories next time this happens.
