By leaving items in the Neighbor's museum while it's available they can be lost once the time progresses and the player gets locked out. I left my camera in the Neighbor's museum, experienced the night 3 cut scene, and then had my camera locked in the museum with no way to get it. I recommend bringing back the open world that was initially promised..... getting then locked out of the museum was just so jarring and disappointing..... I so badly wanted to go back in and continue to explore but couldn't...........
