A mindcrack server that i play on has been having these issues for the past few weeks. If certain chunks are edited in any way, even with world edit by the time the server restarts the chunk will be completely back to normal despite the world saving before each restart. The bigger issue though is the region crash, a large area above spawn will cause the users client to crash giving an internal server error and this in the console

The first assumption was that there was some form of block that the server didn't agree with in the region but after deletin gthe region and allowing it to generate a new one the error continues. So we renamed that world to world 2 and generated a new world for the server and the error doesn't occur at those co-ordinates. So the owner tried replacing the region from the first world with the region from the newly generated world that worked but to no avail. Even if replaced or regenerated it still crashes. The server is also running MCPC+, essentials, world guard and towny. Any help would be appreciated.
Please note in regard to the chunk resets world anchors, chunk loaders, tesseracts are all disabled
