I have reduced Hand Size down to 5 on a run and opened up an Arcana pack. I have used Immolate whilst in that Arcana selection screen to destroy 5 cards (Obviously, my full hand) and am now locked in the selection due to the Arcana choices I have. Skip is greyed out interestingly. Heading back to main menu and back in game reloads the Arcana Pack with the same Arcana choices and same 5 cards from hand, so if I repeat the steps I can reproduce it in an infinite loop.
I can of course just not use Immolate in that screen and progress back on with my run but it wasn't the best run in the world anyway so not too upset, but an odd one for sure!
