Howdy, 

What am i doing wrong here?

Failed to run a 6.00 timer in 'Rustcord v2.5.1' (NullReferenceException: Object reference not set to an instance of an object)

  },

	"o.reload DiscordAuth": 300	
  }
}

I also get this with DiscordAuth

This is an error in Rustcord, not Timed Execute - contact its developer.
