&& fusion doesn't seem to work correctly either. The main difference is that the fusion materials don't seem to matter. Instead, the 1st blank totem vanishes. Adding a 2nd one will seem to work right, but then the modified totem sticks to the cursor instead of going into the alchemiter. Leaving the alchemiter and going back to it reveals that the totem duplicated itself (an invisible one in the alchemiter and one on the floor).

In addition, I can't drop the created item, this case being dressck shoes (dress shoes && vantablack shoes), onto my character, but it shows up as on my character on the equipment screen despite not being visible and also being in my inventory. Also, attempting to remove the dressck shoes duplicates it instead of removing it (I drag a copy of the card away instead of unequipping the item), but I can remove and put on clothing/accessories, such overalls, not created by fusion just fine.
