This has happened a few times, where I will go to drag a card from the Tableau to the Foundation piles, and it gets stuck, somewhat offset to the top right from the cards below it, but then you can't interact with it. It prevents game completion. I will take a screenshot next time it happens and post it, but I figure, if that rings a bell, at least you have the bug report to start with, lol.

Also nice game, :D

Hey thanks! Is it always the top right, same offset? I think I have a pretty clear picture of what you're saying, but a screenshot never hurts. I see if I can reproduce it and then fix it.

You can double click cards to send them to the top.  That might help you avoid the bug until I get it fixed. 

Double clicking deffo works :D I should honestly just be doing that, my discord bois prefer the rotate to the drag, lol.

It is always the top right offset, If it happens again, I will screenshot it for y'all.
