How do you duplicate items in Tower Unite?

Excuse me, could you please elaborate on the process of duplicating items in Tower Unite? I'm interested to know if it's a feature intentionally implemented by the developers, or if it's something players have discovered and are exploiting. Additionally, are there any potential consequences or risks associated with duplicating items in the game? It would be great if you could provide a step-by-step guide or any relevant information you might have on this topic. Thank you for your time.
