We turned on a PRCL FF the day before: 79035. But this 3.6Hz PRCL wobble is normal, it was constant throughout the lock plot and locks before the feedforward was installed (example).
This lockloss looked very normal, AS_A then IMC loosing lock, as usual, plot.
We've lost it at PREP_DC_READOUT twice in a row, during different points of the OMC locking process. Lockloss tool tags ADS_EXCURSION
