Request 96, "Massive Mass Outbreak in the Fieldlands", requires you to clear three of the individual outbreaks within a Massive Mass Outbreak. I was severely waylaid clearing the first one, and the Massive Mass Outbreak disappeared while I was still clearing the second one, leaving me unable to complete the request.
Talking to Mai, the questgiver, has her suggest going back to Jubilife and waiting for another one to spawn. This I've done, but I've gone out on three excursions now, spanning a few in-game days, and another Massive Mass Outbreak still hasn't spawned. I know that Massive Mass Outbreaks don't start spawning regularly until I've completed the entire "Daybreak" questline, and I'm now starting to get concerned that I may have locked myself out of the questline entirely.
How much longer do I have to wait before I get another shot at clearing Request 96? Is there something specific I can do to get the Massive Mass Outbreak to respawn? Or am I at the mercy of RNG?
