Arena lost when tried to reconnect on 3-1 strike

Hi. Yesterday I’ve bought arena match in hearthstone. I’m 3-1 as a Warlock. Today i tried to re-open arena and screen shows me that ive need to buy new one. Can you help me to clear this bug? I’m clearly 3-1 and i havent finished my games. As i proof i even have screen on HearthArena account informations that my warlock is still on the run as 3-1. Namy of my arena account is DannyArena. You can see it as a proof. Im holding myself to buy new one because it was pretty good deck and im sure i was able to win free gold for new one.
