Started relocking about 22:30, initial alignment was fine until SRC steps, where it seemed it was necessary to go through a step at a time to get SRC stable. DRMI was poorly aligned when we were back to locking proper, and took a bit of tweaking PRM and BS to recover. ITMY bounce and roll modes were both high as well, when we got near DC_readout.
