I was not sure where I should post this so I figured it seemed like it belonged here. But has anybody else encountered random giant holes in the ground that go pretty deep? I find these HIGHLY annoying and they make no sense where they generate, it just seems random. Also something else that keeps happening to me is after I generate a map some areas have blocks, you just can't see them, and you can see straight through them, you can mine them and everything but that stay "invisible". Has anybody else encountered either of these?
