I didn't even know that moved to begin with. How long has it been broken?
It has been working sporadically since the ride opened. I talked to a team member there who has worked the attraction since it opened and he explained that the previous mechanism for this attraction was faulty, and that every time they repaired it, the sign would only work for 3 or 4 days then it would stop moving. So two weeks ago they finally took the sign apart and replaced everything, so now it only moves in circles instead of leaning out and in and in circles.
Overall if this is a permanent fix, then a big kudos to the engineer who finally took ownership.
