After updating my game from 17w13b to 17w14a, all my recipes have disappeared, although items can still be crafted.
Loaded a backup of the game and upgraded again to 17w14a and recipes were gone.
Environment
Windows 10 64-bit, I7-5820K, 16GB ram, GTX970, Java 1.8.0_121
Only problem now is that you have to recall all the recipes and then craft them before the recipes show up. Gathering resources does not enable recipes.
