Minecraft 1.12.2
The Camping Mod 2.4.0
Backpacks mod 3.0.1
Singleplayer

Iron Sticks from Camping mod and Backpacks mod are have the same recipes which are overlapped

Thanks for the notification, I think I'll add the knife to the recipe

a recipe conflict also exists with Immersive Engineering iron rods

I mean Immersive engineering is common in most of the larger mod packs the recipe for iron rods is this

Might be easier to just make the Iron Stick recipe match and than use the ore dictionary name stickIron to make the two items interchangeable
