Major beneficial (?) Express arena bug

Searmenis

If you are playing the arenas before they expire, after expiration time the game doesn't throw you out of the arena, but you re going again to the selection screen. You can keep playing the Arena in question, forever, as long as you don't get yourself out.

I noticed the same thing when this first round of Killmonger arena just ended. I was using express mode to match fights and i was still inside the arena after it expired (it usually credits the points of the last fight) but after the arena expired it did not end/close as it normally does. I did one additional round to see if my arena points were still credited to my score and i was surprised that it was and I could still match another fight via express mode. I let myself out of the arena though to end it because i might be thought of Kabam in exploiting a bug. Saw your post and was relieved to see that it wasn’t just me.
Sorry i wasn’t able to get any screenshots.
