Hi.
With artificer, I took the green (?) pearl that's on top of 5P can, swallowed it, and went to the nearby Echo. After being teleported in my shelter the pearl wasn't in my stomach nor in it's spawnpoint or anywhere along the path.
I don't think it's relevant, but I just met 5P for the first time a cycle before doing that and woke up in the shelter above his exit.
