LOCKLOSS_SHUTTER_CHECK keeping us from Observing

IFO_NOTIFY asked for assistance after reaching NLN and having ADS converge because the LOCKLOSS_SHUTTER_CHECK guardian node wasn't nominal (nominal is HIGH_ARM_POWER).

It looks like when the lockloss at 08/10 06:46UTC happened, LOCKLOSS_SHUTTER_CHECK jumped from HIGH_ARM_POWER to CHECK_SHUTTER, and got stuck there with the message "USERMSG 0: run shutter check, then manually take to low power". I requested CHECK _SHUTTER (even though it was already in that state), and then went into MANUAL mode and requested LOW_ARM_POWER. Since the arm power was above threshold, it automatically move up to HIGH_ARM_POWER as soon as I switched to AUTO mode and we got into Observing. I've attached a txt file of the output log since my description of what I did might be a little hard to follow.
