An unusual bug, in which it had occurred for some unknown reason. What really happened, is that when I saw my list, it appears as if some penguins are online, as if there was an event or something. Happened ever since about December or so. But if you go to a server with the same penguin on there, and click the “?” button (Or “Find Player” button), it’ll show you that they’re offline (Or for some, they actually might be online).
Pretty unusual, right? I also emailed in about this to the support. And I hope this should be fixed.
