I made 4 plots, and on the control side, it's subtle but looks to me like OM1 M1 DAMP Y deviated first at lock loss, and on the optics side, all of Y arm optics were already oscillating and then lock loss.

Plot 1: last 33 seconds of the lock - control signals

Plot 2: last 33 seconds of the lock - optics

Plot 3: last 3 seconds of the lock - control signals

Plot 4: last 10 seconds of the lock - optics

Plot 5: fist big glitch at 13:45:47
