Ops OWL Intervention part 3: SQZ Edition continued

Called again due to the squeezer FC, same as last time. I've checked and the OPO temp maxes out H1:SQZ-CLF_REFL_RF6_ABS_OUT, and the adjustment I made earlier to FC1 and FC2  gets H1:SQZ-FC_TRANS_C_LF_OUT almost at 100. The FC is losing lock at atmost the same spot - it's getting to TRANSITION_IR_LOCKING and is saying that green is losing lock either right after loading in the LSC matrix, or after the same spot as before, after changing the DOF1 gain to 0.

I don't know what else to try, so I ran Ryan Short's script for changing the default guardian SQZ states so that we could go into Observing without squeezing until I can contact someone at 13:00UTC.

We've been approved to continue to do Observing without Squeezing until people are able to look at the issue when they get onsite
