Server and plugins versions (please complete the following information):

• Spigot 1.12.2-R0.1-SNAPSHOT
• Plugin Version: RedProtect-7.5.6-b164-Universal.jar
• Java Version: java version "11.0.10" 2021-01-19 LTS

Additional context
I used the command in existing regions, so the problem doesn't lie upon executing the command in unclaimed areas.

I wonder if there's a way to bump this, lol
