Punched cards aren't going into things, including totem lathes, treasure chests, and wardrobes, correctly. If I hover the card over an available spot and click the empty spot, the card will instead be stuck to my cursor. If I click again, then the game will drop the card in front of my character instead of storing it. If I then leave the storage object's inventory, then check it again, the empty slot will have the punched card in it in addition to the one that my character dropped.

The trigger seems to be after || fusion fails with two objects (pressing the button does nothing), then works with another object. I've seen // fusion fail with fashion cables (electronic) failing to be \\ fused by a lighter jacket (but a switching out the fashion cables with a laptop suddenly made \\ fusion work), and a model rocket refusing to be \\ fused by black buttons (but willing to be // fused by vantablack shoes). In case it matters, the punch designix wasn't closed when I switched out cards, and I was using a stack modus that had been updated by the blue box.
