Minecraft Version: 1.12.2
Inventory Tweaks Version: 1.64+dev.146

When a tool breaks it doesn't seem to prioritize replacing with the same material, so something like a stone pick will keep replacing with diamond or iron picks even if I have an inventory full of stone picks.

I couldn't seem to find anyone with this issue, so I don't know if I'm just missing something to make it prioritize material.
