1,17 things not generating on 1.16 worlds

Is the issue no longer occurring for you?

Nope It does generate in chunks I haven’t seen in 1.16 but the ones i have seen have no copper deepslate, and more

I saw chunkbase.com and the website said my world had a geode somewhere but it wasn’t there

Mobs are generating actually like axolotl goat and glow squids just can’t find them in that world

This is working as intended. Amethyst geodes, copper ore, deepslate, and glow lichen are supposed to generate only in new chunks.

Oh thank you
