Item duplication exploit found
I believe I found an item/artifact duplication exploit, though I've not had the chance to try to reproduce it.
I ran into a dandelion artifact floating around near a transition area, I shot at it thinking it might be an enemy, and it floated further into the transition area, unreachable. I proceeded and luckily it gave me an option to retrieve the items in the transition area, so I got the artifact.
I then transitioned back into the previous area, and the dandelion artifact was sitting there again in a bus, near where it was floating when I found it. I excitedly grabbed it, then quickly realised I should've tried shooting it into the transition area again before touching it to see if it came back again! Oh well!
If this is a known thing or if anyone has success replicating this let me know!
