When combined with More Delight, the bread slicing recipe stops working as the recipe overlaps.

Hey friend,

I'm also working on a modpack that includes both mods. The simplest workaround: Include the bread slice from Extra Delight in More Delight's Forge taglist for bread ingredients. Just open the More Delight .jar with an archive tool like 7Zip and drop this file into data/forge/tags/items/bread_slices/, where it will replace the existing file.

wheat.json

This will be fixed with the great entaggening project.
