1.9.2 bug
I noticed when you repair an item it can gain a status (shown by a red aura around the item picture), and I really enjoyed this idea. This can easily be nullified by moving the item into a backpack and then removing it though.
1.9.2 glitch.
When using Animal Fat as a fuel to light a fire, the fire is made but the Animal Fat is not consumed. It doesn’t even take durability damage if you succeed.
I made sure Animal Fat was the only fuel-like item in my inventory.
