I was playing Premier Draft during this screenshot.

I tapped my Osteomancer Adept to cast a creature from my graveyard. I have had three other creatures that I can exile to forage. As I try to cast one, the other three glowed which I assume is for submission to forage.

But whenever I click the cards, it gets dragged and not selected. Was trying different things, like trying to cast a different creature, but still not working. I eventually timed out.

Not sure why I couldn't cast my creature.
