Up a game in a B03 match, I activated the -1 ability of Jaya, Fiery Negatiator to exile two castable cards off the top of my library. One of the cards was Pithing Needle, which I promptly attempted to cast naming "Sorin, the Mirthless". After I hit submit, however, the client froze, with the "Name a card" text prompt visible but no typing box available. I was able to interact with the board, such as the stack, so I wasn't frozen, but there was no way for me to do anything meaningful.

What I suspect happened is that my opponent conceded during the naming, as there were two "win" pips beneath my name as I was locked, and when I returned after restarting the client I was no longer in a match, and was awarded gold as though I had won two games.

While I'm glad the game gave me credit for the win, this was extremely disorienting and I would be glad if you could fix it! Attached is the log file if it is useful.
