playerIsGM Always returns false

For some reason, when I loop through the list of players in a campaign and run playerIsGM for each of them, it returns false in every case, even though two of the players are flagged as GM. Any ideas? var players = findObjs({ type: 'player' });     log(players); //returns array of players     _.each(players, function(item, idx){         var id1 = item.get("id");         log(id1); //returns Id         log(playerIsGM(id1)); //returns false     });

It only returns the current state for a player.  When a player is logged off, they are not a gm in the game, currently.  Ironically, this is the only way that playerIsGM() and my old isGM() script differ.  If you need to know that a player has been promoted to GM status, the only way to do it from the API is to keep track of what they were when they were logged in last, probably in the state.
