Ghosts seem to disappear on this map for some reason, resulting in no ghost presence, no hunting, and no interactions. Unsure how to replicate. I know its possible for the player to fall into the void when transitioning from Jack 1 to Jack 2 (rare and unable to replicate), maybe the ghost is falling through the map?

I also encountered something like this. For me they get stuck in Masumi hallway 2. Happened twice in a row.

seems to happen on the corners of doorways often

I think it happens when moving to Jack 2 to Jack 1 but ghost can never enter Jack Hall 2. Yes, during my testing the ghost did stuck when trying to go to Momoe 2 from Momoe 1 door.

I will just increase collider size of all door ensuring this won't happen. In the meantime if you think you face that issue try finding ghost's spot with flower lamp or thermometer so I will know exact spot causing this issue.
