Saving map problems

[Wuldraider]

I have no idea why, and I've found no fixes anywhere else, but whenever I try t osave a map everything goes normally until it gets to the 'Creating Map Archive' loading bar, which will get a not responding error and shut off, I've verified that when this happens my map does not save, this is happening an annoying amount of times, usually after getting a lot done.

Maybe there's something wrong with things you imported.

Sounds like something blocked WorldEdit from writing the map file.
