I'm on the snapshot released today, but had a similar issue on desktop last week. Occasionally, during draft, I'll be unable to choose a particular card, and if the menu to add to my deck pops up, sometimes it adds the wrong card. I can't blow the card up to see it, and I have to click on another one to "reset" it. Managed to get through a Duskmourn draft with no crash, though I noticed a similar bug. Bloomburrow has crashed on me every time.
Let me know if you need more info. It might be reproducible. It's happened about halfway through draft every time for me.
