I saved this thing of mine, some project I'm working on. Anyway, as I was saving my save (just gave this thing a name). It said "HTTP error: 500 Internal Server Error". I looked at the bottom, after I clicked: Dismiss, and it seemed to have saved it correctly. However.. This save for instance: 866347. Doesn't exist.. And it's the one which i spent lots of time on. :( Help!

EDIT: I have found out, the only way to bypass the glitch is by saving it twice... Still, it's not really good..

@Simon ah, yes it is. Thanks a lot.

The save on the lightbulb i was making.... got corrupted. why does it happen?

EDIT: can it be fixed? (sorry for double post D:)
