Weird bug with randomization.

[GamingInfinite]

When I'm playing in a single player world, I have to exit the world and reenter in order for the randomization to work. When I looked at the log it said it had something to do with one of the recipes in the thing having an empty result, and that was screwing with it. I dunno, but basically during the save randomization of the recipes isn't working. I've attached the log for your convenience. The easiest occurrence to find is at the bottom of the log.

This is an issue with JEI not an issue with this mod technically. Though it's not really intended for recipes to do what we are doing with them so it's expected.

JEI is making sure the recipes are valid when the mod is making them give no result. Have you tried with just craycrafting?
