Not sure what did it to the PSL's FSS, but noticed we were stuck before the PRC portion of Initial Alignment, and DIAG MAIN had the following messages flashing like the devil:
On the FSS screen, the autolocker was going wild and the PZT_MON screen was all over the place.
Since the Autolocker was having issues, I toggled the autlocker off/on and this immediately calmed down the FSS and the IMC finally locked back up.
Going to restart the Initial Alignment. Because the winds are still pretty attrocious.
