Describe the bug:
Nether Quartz "Geodes" often generate partly above the Nether ceiling, with bits poking up above the bedrock. The "geodes" don't replace the Bedrock though.

Versions:
Minecraft version: 1.20.1
Spelunkery version: 0.3.13
Moonlight Lib version: 1.20-2.13.33
Fabric API / QSL / Forge version: Forge 47.3.0

Other mods:
List all mods that you're using; could be in the form of a list of the filenames, a crash report list, a screenshot of
the mods folder, etc. Just make sure all mods used are known!

Logs:
Even if the game does not crash they may be useful!

To Reproduce:

1. Go to the Nether
2. Change gamemode to Spectator and go through the nether roof, looking around
3. Eventually you might find a Nether Quartz "Geode" above the Bedrock layer

Expected behavior:
Nether Quartz "Geodes" should either not generate parts above Bedrock, or generate low enough that this isn't an issue.

Additional info:
Jaden's Nether Expansion v2.1.3-forge is installed, if that matters
