@Lazy - Found a little ♥♥♥♥♥ in the armor mate, in the DLC workbench one or more items that I know of cannot be crafted, one of the mushrooms has the wrong mushroom ID nad is crafting the one you get on the vanilla ARK in it's place, I recommend looking through the DLC workbench and double-checking all the IDs for it just in case.

One of the mods I have requires mushrooms to craft certain items, so yea please fix ASAP.

Should be pretty simple. :)
