Glitch ruining game

First I want to say this is a fantastic game. I play it often to de-stress. But now there is a glitch where a player shows up without any minions and when this player lands near you, your minions think they are supposed to fight (even though there's no one there). This stops you from collecting any more resources. One player (Red player with tag Tribe1739398) has taken to following the players from other teams around, effectively stopping them from playing the game. Really messed up. Please fix this glitch to stop people from doing this.
