OK so what I have now is a docked pea and pomegranate, and it's in the correct place on the pomegranate and yea, that looks right.
I undocked the pea, and suddenly it had apparently picked up the docking marker, or a copy of it, which is floating a couple of meters away from it not attached to anything. THAT''s the oddity.
I also saw one floating around not attached to anything, outside the onion capsule. The one that is sitting in the correct position on the pomegranate is the only one that looks right.
