Impact:
This is a major vanilla bug that is effecting vanilla gameplay in the base game and effecting players survival experience.

This also has a major effect on the vanilla economy as it is changing how much coal is required to be smelting ores and thus effecting the base survival experience.

We have a upcoming map that is utilizing vanilla gameplay and because of this bug it is effecting the maps experience and is causing it to be unplayable.

Observed Results:
It will take 2 coal to cook just one iron ore in the furnace
