Server crash on moon (i think problem with villages)

[kazkas]

I have a problem, with my server, when i traveling to moon, sometimes server got crash, and it writing something about failled to ... moon village , skipping... . And, if y try run server again, it still crash. Only way found to run server without crash is to delete \world\DIM-28\data both files. But why it hapening? Server mod and client mod is 1.6.4-2.0.2.786, forge is 1.6.4-9.11.1.933 .
