Just posting here for everyone to be aware of. It seems timing on concedes in Arena can be a bit wonky. This is usually not an issue in BO1 formats.
Some players have the habit of clicking concede when the opponents presents lethal. (Like myself). If you do it during Game 1 (or Game 2, if you won Game 1), the UI is not clear that you are actually conceding the match.
What happened to me was, I clicked concede in the middle of a lethal attack animation. I guess Arena resolved the lethal attack first, and then took my concede as a concession for Game 2. I would interpret this as a bug, as it was still the Game 1 board state presented on my screen, and not yet the deckbuilding screen. This was the case even after my match was dropped, I moved straight to the home screen from the Game 1 board state. Again, total bummer. Basically it's the equivalent of wasting gems.
Hopefully the devs are reading this and they resolve this.
(No I didn't report this yet as I was quite bummed when it happened. But I guess I'll try reporting later tonight.)
