Mending?
(I know rule 4 says "Add Flair" but I genuinely can't find how to do that. I googled it and everything but it's like the feature never got toggled on in the backend, or I have a UI glitch. I hope the mods are merciful and don't smite me for it)
So I started a fresh game of Matcha flavored using this lovely seed: -8031689365522390945
It plonks you right on top of a village with a ruined nether portal REALLY close by, that has a chest with some loot.
Out of that chest I got a golden axe with Mending I on it. I know by default mending does its thing when you pick up experience orbs, but as we all know matcha flavored technically got rid of that(though I do still hear the ding of me picking it up)
I don't THINK I've seen the durability bar go back up at all, but for a gold axe I DO feel like it's survived an unusually long time.
Can someone who's a bit more in the weeds than I am lemmie know if this mending enchantment is a vestigial holdover from vanilla minecraft or if there's a new mechanic I'm missing?
EDIT: Forgot to include my version. 1.12 using minecraft Java 26.2
