I am having the issue where essentials commands are NOT being cancelled in a specified region. I reported this to Worldguard, but they say it isnt WorldGuards issue, see below:

WORLDGUARD-3733 Blocked-Cmds Flag Not Blocking Commands Created by you
I have set up so a certain region players are unable to use certain commands. Being that I have overlapping regions in this area, I made sure priorities were set and added the blocked cmds flag to all of the regions of higher priority in this area. The commands are not being blocked.

Example: One of the blocked commands is /spawn. But when a player uses /spawn in this area they are still teleported to spawn and they are given the message "/spawn is not allowed in this area."

I've attached my regions file to view in case I set something up wrong, but I'm pretty confident this is a bug.

I'm using Spigot 1.10 with WorldGuard 6.1.2

whatever plugin is providing /spawn is doing things incorrectly then. if they are given the message, it means worldguard is cancelling the pre-command event, and the actual command is never fired off. for a plugin to still be acting on that, it has to be listening to the pre-command event and ignoring cancellations.*"
