So I noticed that there were nearly 30 players online earlier today so I decided to hop on, and when I did I could not find a single person! I explored all the available maps (at least the ones not past Eastern Pass) and no one was there. Usually even with low player counts, there will be someone AFK in The Grounds. It was kinda creepy ngl

So I'm just wondering now, how is the online player count actually calculated? Is it based on how many people have that page open in their browser that lets them into the game, or is it an actual count of the players playing IN the game?
