Whoah, that is a whooooooole lot of show elements out
If it was near the end of the attraction's life, that makes sense, they'd probably just given up. That wouldn't have flown (no pun intended, hah) back when I worked there. If there were elements out, they were recorded by the TD operators and were supposed to be fixed third shift. Some elements took awhile to repair, of course. Like, there was a Dorothy sitting by the timeclock for the longest time.
But ultimately, the attraction wouldn't close for any of those minor effects. Just the out of sync building and a weak tornado.
But that truck is kind of a big deal in Disaster, I would have been bummed if that didn't work!
