Affects Version/s: 1.16.4, 1.16.5, 21w13a, 1.17.1
Fix Version/s: None
I know a lot of people have been having issues with "generator-settings" in server.properties not applying to flat worlds. I did a good amount of searching as was not able to find an answer.
I did come across issue #
MC-182421 which stated it was fixed.
I used the settings from that issue that Bartosk posted:
I tested on 20w18a since that was the version that was claimed to work on.
It worked. But when I tested in both 1.16 and 1.16.4 neither worked. I even tested on the latest snapshot, 20w46a, and still a no go.
In the images, you will see the diamond block world worked in 20w18a, but the same value did not apply for any other version.
