- Go to https://misode.github.io/worldgen/noise-settings/?version=26.2&preset=overworld
- Click the Show preview button
- The world preview looks a lot different to how it does in other versions
Does the same thing with Amplified and Large Biomes presets on 26.2
The preview in the 26.3 version loses all surface rules so everything that uses them appear broken, since that causes deepslate, grass, dirt, and bedrock to not appear in the preview, on top of the 3 aforementioned presets not displaying properly
The surface rules thing is very likely due to new technical changes with noise settings but I'm not sure what causes the weird generation, the generation sometimes fixes itself randomly and I don't know why also

26.2 Overworld, Amplified, and Large Biomes presets with weird generation
Overworld

Amplified

Large Biomes

26.3 Overworld, Caves, Floating Islands, and Nether presets with broken surface rules, having no bedrock, deepslate, grass, or dirt
26.3 Overworld having weird generation and no surface rules

26.3 Caves having no surface rules (No grass, dirt, deepslate, or bedrock

26.3 Floating Islands having no surface rules (No grass and dirt)

26.3 Nether having no surface rules (No bedrock)

I haven't reported an issue on GitHub before so I hope this was sufficient
