What is your Paper/mcMMO/WorldGuard versions?

Check these with:

• /version
• /version Worldguard
• /version mcMMO

[fancypork]

This server is running Paper version git-Paper-496 (MC: 1.20.4) (Implementing API version 1.20.4-R0.1-SNAPSHOT) (Git: 7ac24a1 on ver/1.20.4)

Mcmmo 2.2.013

WorldGuard 7.0.10

[Chew]

WorldGuard probably didn't load, 7.0.10 is only for MC 1.20.6.

You'll either want to:

1. Downgrade WorldGuard to 7.0.9 (easiest): https://dev.bukkit.org/projects/worldguard/files/4675318
2. Upgrade Paper and your plugins to 1.20.6.
