Hello, I am contacting the mod developer with a strange problem. It is about sculk main tomb. I decided to add your mod to my world, where I have been playing for about 400 days and have used many different mods. I am aware that the Sculk main tomb is generated closest to 0,0,0 coordinates, but when I got there I noticed.. nothing. There was the usual Minecraft generation: caves, lava, and more. I did not go down to this level and did not upload deep chunks from the very beginning, so it confused me a little.
I decided to check again if I was exactly looking in that place and the re-generation of the world allowed me to find the tomb. But I don't want to play in a new world purely for the sake of this mod. I wanted to explore it with my existing equipment.
Please give me so advice or comment.

Unfortunately, this is just how Minecraft works. The structure will not generate if the chunks are already generated. Fortunately, you can still play the mod as long as you spawn in a ancient sculk node manually into your world.
