I had a flowstone on my air knight as my opener and for some reason when I go to form my team my earth knight has the exact same one on although I don't have 2...I should probably add its not the only set both can use I also have a vine wood and AA+ in my armory ..i probably won't use 2 flow stones just thought it was weird...the second set isn't showing up in the quest play area so its not that crazy of a glitch... But imagine if someone figured out how to clone gear through the arena... It'd be much harder to track compared to an absurd amount of gems just showing up on someone's account... Anyways its prolly something to look into... If it helps I could take screenshots from my phone if that helps
