Minecraft Version:

1.16.5

Forge Version:

1.16.5-forge-36.1.16

ChanceCubes Version:

ChanceCubes-1.16.5-5.0.2.421 and before that ChanceCubes-1.16.3-5.0.2.394

The Issue:

Before the 1.16.5 update, I used the 1.16.3-5.0.2.394 version of the mod, and in both version none of the chance cubes are spawning in the overworld or as ores. I also tried it with only this mod enabled and clearing the config files with no success.
Tried in multiple worlds too, even fresh ones, but nothing. However getting them from crafting and loot chests in dungeons are both working.
Is there something causing the chance cubes from not spawning at all?

Surface generation has been reintroduced in the latest release. Oregen is still WIP

I see. Then crafting and looting it is until it's reimplemented.

I don't believe Ore/ World Gen has worked at all for 1.16 iirc, but either way yes, It is currently not reimplemented
