About to win an Arena game in a few turns, and got this error

This is so frustrating! I was about to win this game, and was kicked out by this error! All I did was dragged the game window to move its position on the screen.

The system concluded the game as my loss due to unable to rejoin.

I’m not asking to take that as my win, but I do want that loss record removed from my battle log and stats please.
