I am having a bug that seems to have triggered due to two events happening at once somehow. I entered the attic room and there was a girl laying sick, as well as (I believe) the same girl standing up. Curious, I talked to both, the second teleporting me to a different zone to collect some things. After doing so, I was in the laboratory at night, so I returned to the main house.
At this point, a cutscene triggers that expects my character to be coming from the attic, so Lazuli begins walking downwards as if to go to the table. However, since I entered from below, Lazuli just walks against the wall for a few frames until the game soft locks and stops taking input.
I have not figured out a workaround yet since I cannot get into the main house.
