It happened after i copied and pastet blocks on MCedit 2(alpha). I did not exceed the build limit and still it chrashes my save saved game. I really need help fixing this problem cause i build a lot of building and trying to export them all to a new save would take ages. and all mye tp spots with coordinations would need to be altered. FML! Please help me fix this bug.

It could simply not be you, but mcedit2 is in alpha so there will be a lot of bugs. Also I don't think mc edit is compatible with mods...

Turn down your "View Distance."

Nope, didnt work. turned it all the way down. even tried with all the graphics turned down to minimum. Any other suggestions? Is there any other way to recover that game save?

Would i be able to fix this with using an older version of mcedit?
