The fatal error seems to occur every time I draw a Major Arcana card, leaving me unable to complete playthroughs after a few successful lives.
On mobile, attempting to double tap to speed up the text on the events/heirloom screen skips straight into the start of the game, preventing me from choosing an heirloom.
Hoping you'll be able to fix the fatal error soon, as I am really enjoying the game and would love to play more of it!
