WFS locking point seemed degraded; I hand aligned and reset the WFS offsets as usual.
ITMX oplev recentered. While doing so, I noticed an ETMX excursion rear its head for the first time in a long while :
There was no active length control on ETMX, only OSEM damping + oplevs. Afterwards, its still moving around with only local damping on. I'm leaving the oplevs off for now.
