Phasmophobia: 10 hours of Yurei ability science

Описание: ‪@BigMeik‬ had an suspicion about a thing on the Yurei: The Yurei can only use its ability on doors that a player has ownership on. That is, that a player touched this door last. On Multiplayer, this means that a player needs to have ownership (does not matter if host or not). Probably (although this is not properly scienced yet) this means that the ghost has ownership on all the doors upon start of a contract.
In this 10 hour video, i tried to science that. And no abilities while i was away, even though the ghost touched doors like crazy.
But it turns out that this actually NOT the cause. It is something else, ‪@BigMeik‬ found out about this. There seems to be a bug that if a door is closed and the ghost opens it, the game doesn't register it as open. Since the Yurei only can use the ability on a door that is (at least slightly) open. This means, that you never get an ability on a door that started closed or got closed by the ghost (interaction or event) unless you touch that door and open it.
This also affects ghost event for ALL ghosts. Usually, the singing ghost event and the fake hunt will prompt all doors in the current room (that are "assigned" to this room, that is another weird thing) to close. However, if the ghost opened a closed door without a player touching and opening it, the game still thinks (due to the bug) it is closed and hence it will not close.
This makes testing for Yurei more easy, even though the ability still seems to be quite RNG dependent.
It didn't use the 4th ability on the main bedroom door to the foyer because it closed due to an ghost event and the game considered that door closed until i touched it.
There are several ways a ghost can close a door: Close for a ghost event (singing and fake hunt), touching it and closing it and the Yurei ability.

Timetable:
All but the beginning and the last 40 minutes: Mostly me idling in the game, after setup.
Last 40 minutes: Me constantly having ownership over all the doors in the main bedroom.
Missing ability (for my own counter) probably at 42:23, the Yurei closed the front door while it roamed in the foyer.

I apologize for the bad quality within the first hour. Tried my best to cover all doors of that room.
