Summary:

World did not generate new chunks when it expanded the world height.

Impact:

Looks terrible and unprofessional but ultimately does not break the map. Might be a bigger impact on the market as a whole but unknown. Likely to affect players vanilla worlds.

Repro Steps:

1. Open Lucky Present Survival
2. Go no clip
3. Fly down underground

Observed Results:

new chunks were not generated downwards in the main area, but were added in newly generated chunks, yet the bedrock was replaced indicating that it tried.

Expected Results:

If the world height is expanded vertically, new deepslate caves should be generated.
