v3.46.0 (Studio v3.9.5)

Universal RNG Seeding

Even though most things in Celeste are deterministic, some are not!
To solve this issue, CelesteTAS now changes all randomness to have deterministic behavior.

Additionally, all (technically) undeterministic randomness can now be seeded with the SeedRandom,[Target],[Seed] command.
You can refer to the wiki page to read about all supported cases and the ethics surrounding them.

Please report any remaining cases of undeterministic behaviour or randomness!
That also includes deterministic behavior which breaks with seemingly unrelated changes.
