Legendaries don't spawn on new update. Tested with 1 second legend timer in single player to make sure. Also, /checkspawns legendary shows nothing can spawn when it should (same goes for /checkspawns regular all the time).

I have mine at 1.0 chance every 72000
so 100% chance every 1 hour

and it is indeed not working. Not 1 legend has spawned since we updated 7 hours ago.

Forwarded! Thank you!

No legendaries spawning in 9.1.4

I can also confirm I'm having this issue.
I noticed on my arclight server 1.16.5
forge ver. 36.2.39
Pixelmon 9.1.4
and SimpleVoiceChat 1.16.5 2.3.2

The only change i had to make was pixelmon being updated and eveything else works fine.
Also tested in singleplayer .
@Katzyn nailed this on the head /checkspawns, /checkspawns legendary do not work and NO legends spawn naturally, /spawnlegendary DID NOT force a legend spawn but you can still /spawn Zapdos so it has to be the natural spawns.

I am having this same Issue, I never played on 9.1.4, I updated from 9.1.3 to 9.1.5 directly. As well this issue started to happen to me upon updating.
I have changed the config file to make more legendaries to spawn, but no luck. For me, the /checkspawns doesn't work either.
