Here is the error: http://pastebin.com/JcL9fU2V

I don't know what information to give, since it doesn't really tell me whats going wrong... this world, like all other worlds, is in Multiverse, and loads fine for the player. It has no issues with any other plugins.

This world is a plotsquared world but:

xcreative is a creative world too so its not the gamemode

spawn has a custom world generator too so its not the generator

all other settings that I can think of were the same.

Plugin version: v3.6
Multiverse version: 2.5.0-SNAPSHOT-b722
Server version: Paper-826

Hmmm interesting, can you send me your items.yml,config and en-lang yml in a pastebin.com and Ill get to bug testing.

Ok, I can provide that. Do note, however -snipped-

EDIT:

I found the issue. I have this in the items.yml (improper placement of flags):

Doh... I was so exhausted I was still testing it trying to figure out how you got an error... lol. Derp. That's good, if you have any more errors feel free to re-open this issue.
