So this actually occurred before the 8.2.5 update. I assumed my artifice armor got mistakenly deleted as I was working on some builds, but I'm second guessing that now. I only have 4 pieces of legendary artifice armor. Helmet, chest, legs, and class item (all my exotics are getting bumped to artifice). As I am currently putting together a build on D2 Armor Picker, my exotic is a leg exotic, and as it's guardian games right now, I'm having to wear the class item for the event. This leaves my helmet and my chest piece. D2 armor picker is trying actively selecting my chest piece and attempting to put a artifice mod in the chest to boost my stats, but the armor piece no longer shows that it's artifice, and does not have the slot for the artifice mod. The game is acting as if this armor is in fact my artifice armor, but isn't treating my armor as artifice, since I cannot slot the mod into the armor piece. I have saved screenshots of this from both D2 armor picker and from DIM, both showing that it's attempting to put the mod in because the game thinks it should be able to, but it's not recognizing the armor as artifice anymore. I would very much like my armor (specifically chest piece) back to being artifice. It's seriously screwing up my build crafting and enjoyment of this game.
