Using Quark version 4.0-461 on 1.20.1, forge 47.4.0

I am encountering an issue were the yellow corundum is the only corundum color to not grow underground.
Every other color is growing properly.

I am testing on a creative flat world, Y: -60, randomTickSpeed 1000.
This issue occurs even with a pack only including Quark and Zeta.

works for me, are you sure you're not using waxed yellow corundum?

It was.
I even made the same mistake on the 2 different profiles I used for testing.

Now I feel stupid, sorry for wasting your time ^^" !
