OPS post eve shift update

I was about to go to bed when I glanced at the control room screenshots and saw that something looked wrong, verbal was full of MC2 and EX saturations and ETMX drivealign was constantly saturating along with the suspension. I saw ISC_LOCK was also in a weird state, as it thought it was in DRMI_LOCKED_PREP_ASC despite having lost the IMC and both ARMS.

I texted Ibrahim that something didn't look right, I logged in soon after and requested IMC_LOCK to down to stop it which have been a bad move as it tripped the M2 and M3 watchdogs on MC2. After some texts with ibrahim I tried to bring ISC_LOCK to down, had to init it to get it there. Ibrahims taking over now.
