It's fine, as long as I'm able to wind up with enough to get the best ending or whatnot. Thus far I've missed... at least two, and I think more, Hearts? At least one of the Hearts was because the Kelly scene is somewhat similarly bugged? Once you solve it everyone wanders off but you're stuck standing there. I'm hoping I'll be able to get what I need despite that, since I've actually moved on past that area.
Still, bugs are what happens in a game. At least you're not Bethesda. :P
