Can I downgrade or revert a Minecraft world from a snapshot release (1.15) to the current version (1.14)?

I wanted to try the new snapshots for 1.15. I installed them and started playing on my main world save and have made a lot of progress.

Now I would like to go back to 1.14.4 as I want to install some mods, but when I run the 1.14 version and load the save, it gives a corruption warning. When I click continue, it resets the world and all my houses, structures or any changes I had made are gone.

I tried this few times, but get the same result. Is there any way to prevent this? Or do I have to wait for the official 1.15 release to install mods?

Solution 1:

Downgrading is never supported. Downgrading from 1.14 to 1.13 or from 1.13 to 1.12 also causes world corruption. This world is now stuck in the snapshots and cannot be opened in 1.14.4 ever again.

You might be able to use structure blocks to save parts of it and load them in a 1.14.4 world, but that might also fail.
