Some of badlands mineshafts don't generate corridors, crossings and slides.

Some of badlands mineshafts don't generate corridors, crossings and slides, just an empty room. I realized that 50% of them don't. 

Steps:

1. Enter the seed 100. (beta 1.18.0.25 or later)

2. Enter the command, /tp -542 76 -270

3. You can’t see corridors, crossings and slides, just an empty room.

Expected result: All badlands mineshafts generate corridors, crossings and slides.

Observed result: Some of badlands mineshafts don't generate corridors, crossings and slides.
