When I put a Tungsten ore into an Arc Furnace from IE, I get two tungsten ingots instead of two nuggets! I told the IE people about it and they suggested that you register tungsten ore as "forge:nugget_ores/tungsten" instead of "forge:ores/tungsten" :)

This has been fixed in 1.18 since tungsten ore now smelts to an ingot instead of a nugget!

Fair enough, I wasn't sure if I was going to keep it this way just wanted to minimize the amount of tungsten being created until it had a use case.

It is pretty doggone rare on top of only getting a nugget per ore! Considering that, I think Tungsten tools should come with a serious buff, like infinite durability or something.
