There's some instances in which a bingo sheet might not be completable when playing in hardcore mode. While goals, that require you to die, can simply be completed at the end, these may interfere with other goals that require you to finish with a certain action.
I would suggest either tagging all of these goals with "Hardcore" and to only check for that, when a hardcore toggle is enabled; or to add the "Finish" tag to all goals that require dying, in which case a Hardcore option would not be needed.
