I tried to log onto a server running Food Funk, but that failed with the following error message:

Internal Exception: io.netty.handler.codec.EncoderException: java.lang.ClassCastException: com.wumple.foodfunk.crafting.recipe.RotMergeRecipe cannot be cast to net.minecraft.item.crafting.ShapelessRecipe

Installed Versions:
Forge 28.2.0
Food Funk 5.1.0
Wumple Util 3.6.0

Having same issue when putting mod on a server so I'm wondering if maybe a recipe is mislabeled or what not (note I have limited coding experience I actually tried going in and fixing the issue myself but to no success)
