[Server won't stop hibernating]

This wouldn't be a superflat world would it? Same thing happening to me.

[Isn't letting me start a server with superflat.]

Yeah, so basically I have a superflat server that was working until a few days ago, when it did not let me launch it. Don't know why, but it's really annoying as I had a lot of work on there. Anyone know how to fix this?

Cheers.
