Describe the bug
I'm messing around with the latest version of Minecraft (1.16), which means I have to use dev builds. I'm trying to isolate my Factions plugin to only the relevant parts of the server, just the Factions world, which means I'm moving from Factions Safezone claims to WorldGuard regions.

One of the ways you can trigger an item in this plugin is to set a region trigger. Another way is a world trigger. I tried both, which gave me an error in server console.

To Reproduce

• Use a multiworld plugin like MultiVerse
• Set a named worldguard region in each desired world (with interaction flags enabled,etc)
• Use plugin GUI to create an item with triggers for named Worldguard regions, and/or the worlds containing said regions.
• Teleport somehow to place where you expect triggers to occur
• Item does not appear!

Expected behavior
Main function of the plugin is to give players items when specified triggers occur. Hit-or-miss with dev builds right now (understandably so).
