Still need the smelters to work if possible. Problem childs with tinkers smeltery are zinc and osmium (since both cannot be used in the tinkers' smeltery)
While zinc is not that much of a problem (since you can use the smashed ore directly in the crucible of flaxbeard) osmium is one, since you need alot of it for mekanism and using flaxbeard to make all the ingots you need... flaxbeard is really annoying you automate, even with drones (since you need like 3 right-click actions timed from each other per ingot).
So would be nice if all the smelters will work again without needing to edit the scripts ourselves.
And about that: Someone noticed a few pages back (when the topic came up first) that it seems, that when you disable vanilla-furnace recipes, they get directly disabled in smelters of ender io and mekanism, too. (at least enabling vanilla-furnace recipes seem to enable the other smelter's ability to smelt stuff again, too)
