Bukkit

Hi,
We can't block BetterAlias command with FLAG of world guard ! (blocked-cmds)
And even if I use PermissionsEX to remove the permission in a world, the player can do it.
The issue is that I added to my plugin if /portails (an alias) is ran then run /spawn
So if player is in the WG region where he can't do /spawn, it wille be disallow ! BUT if he is not then he will be teleported to spawn.
BUT BetterAlias can't be canceled AND the priority is LOWEST >_<

Pleaaase help x)

            event.setMessage("/spawn");

it works finally with loadbefore: [BetterAlias]
