September 2025 Version Update

Everything resets when a zone is taken offline or server maintenance occurs. Back in the 75 era people would run to dragon's aery right before a maintenance because Fafhogg was guaranteed to spawn in its 3 hour window right after the servers came back up, even if it was killed an hour or two before maintenance began. Since the NMs are randomized when they spawn it's only logical a new set would reappear after the update.

Didn't they say the nms would respawn each day at jp midnight?

Id be more concerned if the progress was reset by maintenance and if my server was gonna miss out on the enhanced chest

I have not been to Temenos yet, but this is a list of NMs that come up for Apollyon based on name of reforged AF:

Apollyon NMs:

Atrophy (RDM)
Reverence (PLD)
Ignominy (DRK)
Totemic (BST)
Brioso (BRD) *confirmed popped
Orion (RNG)
Wakido (SAM)
Hachiya (NIN)
Vishap (DRG)
Foire (PUP)
Maxixi (DNC)
Geomancy (GEO) *confirmed pop
Runeist (RUN)

Pillager's (thf)
Assimilator's (blu, horrible)

Yesterday came across Vitiation (RDM) in Temenos.

Just from that and your collection alone it seems very safe to assume all the names/jobs are easy to predict.

it's not a mystery; there's a version for all artifact and relic reforged names. both wakido and sakonji have been found, both geomancy and bagua (and their luopans), yadda yadda.
