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.
I'll get a move on looking at those, thanks for the bug report! And just to be clear, by rest area do you mean the Command center with the white floor, or the Lab with the red floor?
