But you can't for example, remove plains biomes from the overworld and keep everything else the same, something you could do in 1.18.2. you would have to completely remake the 1.19 overworld biomes preset (which is unknown) but without plains biomes.
Added a screenshot of chat settings.
Is touch screen mode on?
options -> controls -> mouse settings -> touchscreen mode
Why is this marked as a duplicate? It clearly isn't.
This is actually a bug with my datapack.
The changelog doesn't say the technical world gen changes, so I had no idea why this happened until recently.
Pls help
