The game data I was playing was previously played in the beta version of "Cave and Cliff Updates".

However, due to a terrible bug caused by the disappearance of items, I ended playing in the beta version and resumed playing in the official version.

Now with version 1.18, no new formations are created below the old bedrock in the already played area (old bedrock remains the same), and there are no formations between the newly created formations. It was generated.

If possible, modify it so that the basement is generated correctly.
