So I recently discovered a reoccurring bug which displays that a player is in a game, when they’re not.
You can see that the game they’re in is closed, so they’re likely editing it; but they’re not actually playing the game. This could be a bug that occurs only when the player is testing the game (??).
I’m pretty sure it’s due to Team Create and not a bug.
Team Create uses game servers just the same as if you were playing the game. It will even display “x Players In Game” if viewed from the creator’s profile or under the Games tab on a group.
Instead of a bug report, you should submit a feature request asking for a separate icon for players in-game regularly and those in Team Create
