Waited for dozens of game days with latest version and no single wilden mob spawned at any biome

Sorry I didn't read update notes about wilden dens, but could you please provide an option to generate them in already present chunks in old worlds?

Anyway disabling world spawn is really bad design decision, slowing down progression and breaking skyblocks, please consider this feedback.

Mob spawns can be adjusted by users in 1.19 forge by using biome modifiers datapacks.
