Duplicate Zonai Devices.

To duplicate zonai devices stand on hover stone and be near the center of the hover stone.
Save the game so you do not lose/waste devices.
Select rockets first as a test, 1 to 10 it doesn't matter, press BY at same time, same as ingredients glitch.
You should get the prompt
" You can't take that out here "
If you do not see the message, move forward a little and try again, once you find the sweet spot where you see the message and increase inventory, load your save file. Repeat the process and enjoy.
Sorry I do not have audio explaining, I do not have a set up, I just submit small videos I find interesting.

Sorry it doesn't work for you, when you use BY does it still use inventory or does inventory amount stay the same for devices on your version ?
