Solved Server crashing + Creates new world?

Hello.

I have made a world named Novus using multiverse. Everytime I stop or restart the server it would crash and create a new world and I would lose my items. My Novus world is still there however my items are forever gone. I don't want to create those "world" "world_nether" "world_the_end" worlds, it just does it self.

Edit: I have fixed this.
