I have always used vals crafting melt down since the beginning, always worked just fine. when i installed my enhanced perk points or perk point plus, whichever it is, it still worked. it required certain skills to be picked to access certain technical usages of the smelter. however it would still have some misc items present.. arrows or coin to gold etc.. etc.. could take raw hide stuff apart some leather stuff apart.. etc etc..
anything that was derived of ore itself had to be its specified line.
anyway, now none of that stuff is showing up --- is it not compatible with recent updates? or do i have to go searching around see what the issue is. and i aint that bright.
