So, I FINALLY got the answer to what happened here, from the inside. It was an after hours troubleshooting test by maint. techs in which an illegal trick was used to override an important sensor. It was a mechanical trick to fool the system computer.
The screen was hit by an rv and the kuka system and screen were damaged, but I was told that residual damage was minimal.
I suppose that the closure was used to thoroughly check the track alignment and footings... everything. It would appear they had other scheduled refurbs that they fast tracked into getting done during the shutdown.
One or two of the techs were fired.
So, after much ado, there you have it.
