Hi Klei,
While playing split screen offline, I entered a worm hole, after exiting and walking a bit around i found some bees that ultimately killed me while I had equipped a piggyback. When checking my map I found that it had marked on it a total of three piggybacks, one was of my brother, the other was the one that I had equipped, and the last one I didn't knew of, so I asked my brother if he created another, and he simply answered that he didn't. While in ghost mode I checked that exact third spot and the locator just disappeared, and of course there was no pigyback but I think it's important to say that it was near the entrance of the worm hole I entered.
Not a game breaking bug, but hope it helps
Steps to Reproduce
