0004926: Forgotten beasts arrive in the Underworld
After piercing an Adamantine vein and unleashing the minions of Hell (and then using a trap to safely kill all of them), several forgotten beasts have decided to arrive in the Underworld. I was under the impression that they were only supposed to arrive in the normal Cavern layers.

Have you modified your number of cavern layers appearing in the world? Wondering if the compression of appearance layering might be overflowing into hell as it seeks a spawn point.

All worldgen parameters are standard - the region has 3 complete cavern layers and a magma sea above the Underworld, just like it's supposed to.

This has happened to me too. After unleashing demons, forgotten beasts spawned in the underworld.
