Its -for the most part- a normal server me and my friend play on, but recently, I've noticed in the distance during the night, quick glimpses of what appear to be players, despite nobody else being on the server. Im losing it.
What are they?
Edit: one or more of them dug a hole under his base and were apparently living in there, shortly after their items along with any trace of anyone living there vanished. They knew I found out.
