I'm only seeing this on the foil stone card in my deck. I noticed throughout my run that this was happening, and was succeeding for the other stone cards. I -think- this behavior was consistent along those lines.
Nebula deck, green stake.
NOTE: Yes, I'm using steamodded, but the only mod I have is https://github.com/Kooluve/Better-Mouse-And-Gamepad, a quality-of-life mod for controls. I don't imagine there's any overlap here (but obviously that could be wrong).
I'm picking this game up after a long break so I'm questioning a lot of mechanics, but I think that is also weird behavior
