First, why is the filename load-furn? I reported this issue to the "loader furnace" mod author.... and they were really confused but finally pointed out it was the wrong mod.
Ok here's the problem.
The recipe for Steel in Krastorio2 in the 2nd tier of recipes is messed up.
It requires 10x the input materials, take 10x as long, but produces 100x the output instead of just 10x.
Also unlike all the other recipes, this one does not have the adv. furnace overlay on the recipe icon.
All the other 10x recipes are fine, just steel is out of whack
any ideas about this?
Here's what I see from the furnace for the recipe
here's the recipe selection on the 2nd tier tab
and here is the recipe as it is displayed in FNEI
