the snowy tundra is the only biome that generates

What is the world seed?

I have made three worlds, and they all were only snowy biomes and I deleted the worlds out of anger sorry

We need to have steps to reproduce the bug in order to confirm it. If this happens again you may comment back here with the world seed.

it happens  when you create a world and the game freezes because i got it to happen again and when I tried the seed again to try to reproduce it I noticed the world gen screen seemed less laggy and when the world actually generated the terrain was the same but with a different biome.

How do you get the world gen screen to freeze? Could you attach a video?

I can't cause I don't play pc so I can't record it

What device does this happen on? You put "multiple" on the report, but it seems like it's probably dependent on a specific device. Also, if it still occurs, please update the Affected Version/s field.

I experienced this on my tablet, switch and xbox.

Maybe you could use your tablet to record a video of it happening on your Switch or XBox?

Since this is not reported by anyone else but you are experiencing it on multiple devices, maybe it has something to do with the sign-in/account data.
