Giant world generation error?

[Awesomecross97]

So I recently pruned my Tekkit Lite world in MCEdit.

When I started to walk around and the chunks started loading, the server kicked me for Internal server error and the server console spat out this;

Any ideas about how to fix this?

Try restoring it from a backup.

And don't use MCEdit on modded maps - it's only built to use Vanilla Minecraft blockIDs. With mods you have 4095 block IDs, while Vanilla has 250. This leads to MCEdit completely screwing up any blockIDs it doesn't recognise in many cases, and it's more than likely that this is the cause of the error. I'm not sure if this crash actually is caused by McEdit, but it's worth avoiding, unless you like mining turtle ore and netherbrick fence trees.

I tried it with a world that wasn't mcEdited and it is still doing the same thing.
