Yeah, I've found that when I use the method the guy who makes PermsEx recommends to detect PermsEx, it throws that message quite a few times (no idea why). It's almost as if the plugin is being loaded quite a few times, since that event only occurs during the onPluginLoad event. Anyway, your problem is really weird because I also use PermissionsEx on my server and I have no problems. Very strange. Are you sure you gave yourself the permissions to use the commands? You need the taien.th.admin permission to alter settings or view /hunt help, since /hunt help is only useful for admins. The only command any regular player needs is /hunt. /hunt help would be useless to a regular player because they can't do any of the commands in it. Make sure you have given the taien.th.claim, taien.th.notify, taien.th.hunt, and optionally taien.th.hunttool permissions to people who you want to be able to find chests. EDIT: I could add a separate '/treasurehunt' command if you want for basic info for players who don't have access to the admin version '/hunt help'.
