I have a full set of enchanted nether armour that includes a helmet, chest-plate, leggings, and two boots (one with depth strider and the other with frost walker). I recently put the full set of armour in one of my inventory chests after wearing them- I don’t like to have the armour on all the time as I die a lot- and I go to my inventory to put it back on and it’s all missing (except for one pair of boots that I didn’t put on in the first place). This armour was fully enchanted, and I’m certain I put in in my chest.
