in the newest snapshot "17w14a" if you update a world from previous versions your crafting recipes get deleted

I logged in normaly and updated to snapshot 17w14a and played. I lodded a world that was one snapshot behind (ofcourse a backup) when I joined the world I was in survival. When I tried to autocraft something I saw that all my crafting recipes that I had unlocked so far in that world. From pure curiosity I tried to join the original world (blaming the backup for being faulty) when I joined the same thing happened. When I joined back in the previous snapshot the recipes re-appered. Also I tried retriving the recipes by going to gamemode 1 but every time I grabbed a material it wouldn't unlock it's recipeS emphasis on S because through commands I couldn't retrive propertly all of the recipes too.
