Prevent Worldgeneration on each start...

Hello,

we running a multiworld Server (R4) with the multiverse plugin. We've removed an old world called "oldworld" but bukkit generates a complete new world on each start.

We already removed this world via "mv delete oldworld" and removed the permissions from PEX, folders deleted.... We removed the multiverse plugin for testing too, but bukkit generates the world again on start... I am really confused ;/

Can someone gimme a hint?

Solved, after removing each plugin step for step....
