Owl locking notes

Alerted around 645 PT about initial alignment not completing. I found it with MICH not locking, but flashes seemed a bit off. I tried realigning via the camera and trying to maximize the flashes in AS_A. Even after getting a good spot on camera and having good flashes, it would diverge when tring to lock. MICH dark was the same. I tried to skip this state but SR2 alignment wouldn't even lock, and trying it by hand seemed that there was something very off.

Richard had told me that he set a node to INIT around 630PT, trending back it looked like in Input_Align. We've been having issues with this state recently, I guess that makes sense. I then tried this state and it locked without issue. I then tried PRC, no issues. Back to MICH, same issues as before. Tried skipping it with a well aligned spot on camera, and ran into the same issues with SR2 alignment.

I'm handing off to Corey with the suggestion to restore alignment to the last alignment Oli did and then trying an alignment since I was able to lock with this earlier.
