Bug Description

In my world "creative" (with "creative_nether" "creative_the_end") is not allowing items to dropped and the minecraft:item to be summoned

Steps to reproduce

Drop an item in world "creative", "creative_nether", "creative_the_end"

Agreements

• I have searched for and ensured there isn't already an open or resolved issue(s) regarding this.
• I was able to reproduce my issue on a freshly setup and up-to-date server with the latest version of Multiverse plugins with no other plugins and with no kinds of other server or client mods.

[NeverGrowUp]

This appears to be another plugin interfering. Not something multiverse controls, nor limits by worldname.
Worldguard?
