Pretty psyched at what you're doing here man, reminds me a lot of an old bukkit plugin that I can't remember the name of any longer lol.
But anyway, I'm having trouble getting tags to display properly using nucleus. I'm running the /tag channel global G command trying to assign a tag to my global channel, it says "tag changd to G" but there is no tag added.
Upon running this command, I don't get any errors, but if I try and chat in a channel that I've tagged, it gives me the following error I've pasted below. My message still gets sent out, from what I can tell this isn't a problem with simplechat, as the channels work fine, I have a sub acct I'm using to build this and wanted to check that first.
I've got a lot of plugins, craftbook, foxguard, lottery, luckperms, adventuremmo, nations, noxray, nucleus and mixins, nuvotifier, playershops, simplechat and simpletags, totaleconomy and worldedit.
This error also occurs when I try and tag specific players as well, the tag says it's applied, but when they chat there is no tag and this error is generated with any messages that are sent.
Any help would be greatly appreciated!
