World Generation Got WORSE After Downgrading my 1.21.6 World To A 1.12.2 World And Then Upgrading Back To 1.21.6

Hi So I Made A Mod Using ChatGPT And To Test It I Downgraded My Creative World Named Snow From Version Vanilla 1.21.6 To 1.12.2-forge-14.23.5.2860 And As Usual 1.12.2 Does Not Have Option To Create Backup And Load So I Clicked Use Anyway And As Expected My World Corrupted And When The Mod Did Not Work I Upgraded That World Back To Vanilla 1.21.6 And I Ended Up Being Spawned In The Same Ocean That Was In 1.12.2 But Many Mobs Fell From Sky Including Animals, Creepers And Skeletons And The Hills Around The Ocean Just Got Corrupted With Ore And Block Generation Going INSANE With Naturally Spawned Glazed Terracotta, Bricks. Also Dirt Gravel And Stone All Got Messed Up

What did you expect? Downgrading is a very risky action for a minecraft world, especially when you downgrade to such an old version

Can confirm, downgrading a Minecraft world can have detrimental effects on it. Generally try to avoid doing this if you can!

Modified versions, outdated versions, and downgrading worlds are not supported.

Please only report bugs in the latest versions of the vanilla game (currently 1.21.7)
