As a comment, going to talk to M as V or G during the escape part plays the dialog for the bat hunting. I feel like that should not be the case, particularly since the other two characters aren't available to speak with using any of the characters.
Probably shoulda mentioned this last patch, but forgot; going to the hanger after getting back to the base (may or may not require going to the lab first, forgot to check before saving) and inspecting the vehicle has you prepared for the mission to go to Hilly Hill, and upon accepting has you walking around the initial map with the saucer version following. No interactables exist on this map, making it a softlock. Amusingly, each of the characters in the menu have different facial expressions.
Skipping the maze cutscene skips the lamp; unify ending with two milk, the machine wouldn't run, and then (having drank one of the three milk to get two milk in the first place) trying the machine in the rest area made the screen go black.
