Game not stopping for Instant/Stack responses
When playing a game, the game bugs out and does not pause for stack triggers/interactions.
I just had a game where the opponent played a card and I had mana available to counter.
The game did not stop for me to interact with the stack.
This is extremely bad and might as well not play if this is the situation.
I have also witnessed someone on Twitch with the same problem, so it definitely is not isolated.
Playing on PC.
