Tonight I found the ITF safety tripped after 5 failed lock acquisition attempts; however, after setting correctly the failsafe state (LOCKED_ARMS_IR), the automation immediately requested LOW_NOISE_3 again (Figure 1).

This has happened already a couple of nights ago (Figure 2): I think it's a bug of the newer Autoscience feature, there will be some investigations offline tomorrow.

I put the ITF manually in LOCKED_ARMS_IR.
