[Bug]: Snow Layer does not Generate on 1.18+ Versions

[MarcatoSound]

Is there an existing issue for this?

• [X] I have searched the existing issues

Current Behavior

As of OTG Versions running on 1.18 and above, the snow layer generated in biomes with a temperature value around 0.1 no longer appears.

Example biome used: https://pastebin.com/XcbY7Zfn

Expected Behavior

On 1.17.X and earlier versions of OTG, snow generates at the highest available air block in any biome with a temperature value around 0.1, including on top of generated objects such as trees. This step seems to occur after cave carving, or at least recognizes "cave air".

Which platforms have you reproduced this issue using?

Spigot/Paper

OTG Version

OTG 1.18.2 0.0.27

Platform Version

git-Purpur-1592 (MC: 1.18.2)

Steps To Reproduce

1. Use Paper (or a fork, such as Purpur)
2. Run OTG on 1.18+
3. Load up a world with a biome (in this case, the provided TEMPLATE.bc) that has its biome temperature set to <0.1
4. Look with your special eyes
