When the game crashes due to a network error - e.g. personal wifi goes out, and the user quits MtgArena to try and restart, the game forces a verifying of files and a 1gb+ download in many cases. Not sure if this log contains the requisite input (prob not) because I had to restart the game. Mac client installed with Steam. This seems to be a repeated bug every time I've had a wifi disconnect, or tried to start up MTGArena while not connected to wifi.
