There must be some bad connection


Somewhere between CDS model restarts and the IFO venting, ITMX got stuck.

I shook it loose using the usual bias slider technique. It appears to be free now, I was able to lock the green beam on a TEM00 mode without touching the green input pointing. The ITMX Oplev spot has also returned to within its MEDM display bounds.
