Do you have a save from before the scene starts to go back to? It sounds like your game's variables got mixed up somehow and it thinks you're in the middle of the cutscene. I have absolutely no clue how that happened, the only way to fix it would be to start the scene over. Did you save and quit at some point during the scene? That might've messed something up, if you remember when it might help me figure out what went wrong.
The one time I saved was after I left the room, only noticing too late that Jay and Janet hadn't walked outside with me. I was hoping you had a way to fix it if this was a common issue. I do remember that I saved once or twice during the "food hunt" part. The only save I have before this glitch is before I did all the side quests for the other characters, a few hours worth of time.
In case this isn't fixable, are those side quests going to be important in any way later in the game?
The side quests aren't called for anything major right now, just occasional dialogue branches where it'd make sense to mention something that happened in one. I'll probably add cheat codes to complete them at some point so that people who lose their saves or are in situations like yours can fix it quickly.
