While trying to make the Changes found in this alog 72795

I was in the Process of making the changes and accepting the SDF's diffs to go back to OBSERVING and the IFO Unlocked It's self.
We Got back to NOMINAL_LOW_NOISE, but couldn't get back to OBSERVE because INIT_ALIGN , ALIGN_IFO and SQZ_MANAGER were "NOT OK". According to the H1:GRD-IFO_SUBNODES_NOT_OK list.

LOCKLOSS 7:15 UTC Lockloss due to button press.
I Tried Reloading INIT_ALIGN to see if it would become "OK", and then I thought, Oh I should just take INIT_ALIGN to DOWN and Back up to IDLE.....  WHICH THEN UNLOCKED THE IFO.  OMG I'm So Sorry Oli.
