Is this a bug in index 0 of GetLeaderboardAroundPlayerResult in the position field?
Notice the player "TopTuna3378" position is 1 at Leadboard[0] for result, however the next positions are 23 and 24.
Looking at the leaderboard in Game Manager TopTuna is showing as position 22. Therefore why doesn't the GetLeaderboardAroundPlayerResult return position 22?
