Lockloss at 2025-08-01 22:02 UTC after 3 minutes in NLN. We couldn't go into Observing because of SPM differences causing SDF diffs in the guardians for ISIHAM2/3/4/5. Last time we had this, I asked Jim what to do and he said to just INIT the guardians, and it caused a glitch, but we did not lose lock, and he said INITing them should not cause glitches or locklosses (85809). Today, I did the same thing and went to INIT the guardians, but when doing it for the first one, ISIHAM2, it caused a glitch and we lost lock from it.
I don't see anything fishy going on on the guardian side of things here. When the ISI_HAM2 node had rerun the HIGH_ISOLATED state, after running through INIT, it changed a bunch of the GS13INF gains. See the end of the guardian log for the ISI_HAM2 and SEI_HAM2 nodes in the attached txt file. We then saw these changes later as well in SDF (alog84140), so the large earthquake script button might be conflicting with this.
