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?
