Unloaded plugin Rustcord v3.2.3 by Kirollos & OuTSMoKE

I'm having the same issue.  I've got the latest version of the Disccord extension, and just updated DiscordCore and DiscordAuth, and both of those are now working.  Just having this issue now with Rustcord.

This is all after having to do a full server reset, so I assume we didn't have issues previously because we were on an old version of the Discord extension.

Hey @zalexz, I just dug around more and found that the config file has changed a LOT in the latest version - after migrating to the new config it worked.
