If I add a recipe that produces other items, NEI will show the new recipe.
But if I put the material into the machine, I still use the previous recipe.
(For example, I set up four planks to make one furnace. NEI shows that four planks can make one furnace. But when I actually make it, I still produce a workbench.)
The materials I added include ingot, stick, long stick, plate… I basically made one of the materials I need to use.It wasn’t until yesterday that I realized it was unnecessary.
