Btw I think I found a bug in Window (Resizable) mode. Not sure if it only happens there. I slightly resized the window, played a few matches. And while organizing my hand I accidentally let go of LMB while grabbing the card near the bottom of the screen, to which then the card got stuck floating there. I couldn't grab it anymore and just discarded one of my other cards to end my turn and the game gave me a full hand while not taking into account the card that got stuck. So it functionally let me discard an extra card. The card remained visibly stuck for the remainder of the match but it does disappear after match ends. Nothing else happens while it's stuck, it's only just... there.
Now, this is a local game for fun, but it is still a fairly easy to exploit trick to pull more cards per turn if you end up bricking a hand. I ended up having it happen again the same way so it doesn't feel like it's difficult to replicate the bug. Doesn't feel like a priority type of bug like the ones that got their inventory wiped. But I thought I'd come here to let you know about it if no one had stumbled upon it yet.
