help (solved) Lopunnite Broken (Ignore, I'm dumb)

[Aurus]

EDIT: Duh, X, Lopunnite, what am I doing. My bad, ignore this.

Using the newest (and 29-01) PKHeX, if I attach lopunnite to a Pokemon and send it through the browser box transfer method (in this case, to X), in game the item slot shows up as blank (as in an empty space, not the usual (none). If I remove the item, a nameless item can be sent to the bag, which then crashes the game when accessed (or perhaps when you motion to view the item or the pocket, only did this once so not sure on the exact point it breaks). Haven't encountered it with other items I've tried. Let me know if there's anything I can do to help diagnose the issue or whatever.
