When i type /world create EpicJungle:Tropic 3252346547
World just wont generate!
What's wrong?

what multiworld plugin you're using? Also is there any console output? And have you tried "/tropic EpicJungle 3252346547"?

I'm using My Worlds v1.47 and when i try create it by "/tropic EpicJungle 3252346547" it seems to generate but after generation is completed chunks do not load on any world.
PS:
There is not any console output that is not normal

Hmm?
