I found my world tour ranking error after US Open.
I play 3 players in Career mode and when US open is finished. And I click on game to process to the next week tournament.
The ranking system still quite normal and process by point from US Open.
Such as my 3 players reach World No.7-No.9 and also AI players (Kerber) who is currently no.2 and she reach US Open Final. So she still stay at No.2.
Then I closed the game and I open it again. The world ranking starting error. My players climb up to No.2-No.4 and Kerber fall to No.5.
Also another AI players, their ranking are also changes. Some players who stay around Top 20 and when system error, they falls out of Top 100.
I try to look at System file. They said some players are exceed more than 20 in RankPerYear. So I try to edit all those players.
But the world ranking is still error.
Or maybe because I adapt my Tour.ini file and put some more tournament on each week after US Open???
(It only happens at World Ranking but it's not effect to Race Ranking.)
