Okay I have a hypothesis.
Baring in mind that Fanny has been messing with timelines.....................all vlogs could be very old and, in fact, the Castle (Sic), the Chapel AND the lake have already been fixed up and we've just metaphorically been asleep!?
Sort of like Bobby Ewing (Dallas) dying in a car crash and his wife wakes up and it's all been a dream and she finds him in the shower.
(this has also been put forward as an explanation for Harry and Megan's current stance as compared to the Oprah interview) - could be plausible and it's US who have just dreamed it all. All the falling down walls, the lack of progress, the trips overseas avoiding the Castle and it's problems etc.
What do you guys reckon?
