two times in a half hour means you have mods that change raids
raids occur once every 46min (and there is 20% for raid)

so getting them under 30min means mod (and since there is mod... it could raise 20% to higher number too)

Second, letting fulings attack in the meadows, which is supposed to be a relatively safe biome? I really don’t like the idea of going around getting supplies and getting attacked by fulings in the meadows, and not even in range of my base where I can get some shelter.

it's nothing new
and since you already killed yagluth (the fuling boss), fulings pose totally no threat, no matter the biome you are in

no idea where you got "mountains-only" idea, but it was always mountains+plains
simply devs finally fixed this old bug that prevented it from spawning
