Issue description

Hummmmm, is that normal that I found Normal stone and it's varients Diorite/andesite around Lakes in my dimension??? This dim also have it's own block for stone...

Issue comments

I could be caused by some other generators. I will check out whether this stone can be removed without any heavy hacks and in such case fix this in next releases.

When making biome you are defining only grass and dirt while in custom dimension you have to use your own rock so check if you didn't used any rock type as base to your dimension 

I have checked and it seems that if the lake is lava material based, it will spawn stone around it, but right now I can't find a workaround for this.

Hummmmm…..

Then... If we create a custom fluid with same texture and color as lava? That might fix this issue?
