After some new of the patches between 21.08 and 26.08 appeared a bug with draging cards that makes it impossible to play with. Normally you can click and hold with left mouse button then drag it in the zone where you want it to be then relesa the button, and everything is alright. But now you have to click to take the card and click again to release the card. In some cases, like with "target opponent chooses piles" effects and mulliganing, it works critically unreliable, because you can't actually interact, or pull the cards in any direction, the game simply doesn't react to it. You can't even click on them, the game doesn't react.

I hope this is gonna be fixed as soon as possible.
