Feature and Terrain Dimlets not generating in worlds

[YesVRC]

Issue description: features won't spawn and the terrain won't change to the specified block

Steps to reproduce: Make dimension with feature and/or terrain dimlets (optionally with block dimlets before either)
Versions:

• Minecraft: 1.18.2
• Forge: 40.2.18
• CompatLayer (only if on Minecraft 1.10 or 1.11): N/A
• McJtyLib: 1.18-6.0.20
• RFTools: 1.18-3.0.12
• RFTools Dimensions: 1.18-8.0.10

Possibly incompatible mods: Rubidium, ModernFix, TerraBlender, BiomesOPlenty

Relevant logs, if any: Not a crash but in the server logs it does confirm that the feature dimlet with its block type is recognized, they just don't spawn.

I don't understand? You are not using a feature dimlet in your dimension? Can you explain what the issue is exactly?

[YesVRC]

I do have a feature (cube) dimlet with thermal:sulfur_ore as the dimlet before it
let me get some screenshots
couple other players tested some dimlet combinations and they couldn't get features or structures to generate
