Note: I'm not sure if the following happens in the beta, but I'm going to assume it does.

     I'm enjoying the new Caves and Cliffs experimental setting! The caves are immersive, giant, fruitful, and nonexistent. Surface caves are extremely hard to find. When I find one, it is always underwater. I'm convinced that there's a bug preventing the caves from generating, and I'd enjoy it if you fixed the bug! If this is intentional, then it's certainly a bizarre design choice, but I know that it's the authentic survival experience for me, and that's all I want. One more thing: there is no Blackstone in the caves under y-level 0. Unless this is one of the countless imparities, I'll assume that this hasn't been added due to the feature being experimental and unfinished.
