Battlegrounds Lord Barov Gamebreaking Bug

[Nirot-2460]

I just picked one of the many reports on the discover bug:

Discover cards not showing choices

This is the second time I have encountered this issue. When I play as the priest and use a card such as renew, or eternal servitude, the discover choices do not appear onscreen. This prevents me from playing any other cards or ending my turn until the timer has run out. At which point, a random choice is made for me. Both times this has happened to me were in ranked matches, and needless to say, I lost both matches.
