Describe the bug

When nearly completing a playthrough of RotN, I noticed that Skydrakes ceased to exist/spawn after a certain point in progression for gamestages. My hypothesis is that after getting through a certain gamestage somewhere around enterBeneath, Skydrakes stop spawning in the Aether due to some obscure bug.

To Reproduce

1. Acquire gamestages in order until the Aether.
2. Observe the Skydrakes spawning normally per usual.
3. Continue on to progress to further gamestages.
4. Observe that Skydrakes do not spawn anymore, whether it be day or night.

Expected behavior

I expect Skydrakes to spawn regardless of how far into progression a player goes.
