I have run into an issue where the game soft-locks on a black screen when selecting to engage with the second scene at the restaurant for after having done it the first time (one unlock done, but not the second) The notable difference I found being the scene would play from a new button instead of replacing another scene's button.
Not sure I can offer any further information, but I'll try to check back here the next couple days. Hopefully the vagueness to avoid spoilers isn't an issue.
