It has currently happened a lot to me that the game freezes at a point in the game. Commonly during matches and at times after finishing a match.
The game literally freezes coincidentially after using a card or after some animations and once the match finishes without even showing the gold earned or the interface after a loss. I had to reset the game immediately during matches, but once reconnected would make me lose a turn which most of the time would cost the game.
Please do check up on these issues. I am literally unable to test out my decks after the expansion after a number of losses just due to this issue
