I was just playing in arena and noticed that immediately after losing my fight my rank went from 13-20. I'm not talking a minute or even 10 seconds. It seems as I was in a fight, someone else was already in a fight which I thought was impossible. I waited for my last fight and immediately bought another 5 fights to regain my rank. Immediately after winning I spent crystals so I could do a last fight before payout and I couldn't because someone was fighting me. How can this be? Was someone cheating or is it just a glitch.
