Yes, but those what seemed to be changes made around the 18/05/16 are not logical changes; they are more likely to be errors or unintentional changes. How can you explain the fact that in some cases, it was very clear that the players were disobeying the orders given to them, as if they were doing it deliberately? How can you explain the fact that suddenly many defensive players went absent in games? How can you explain the fact that a good majority of players that had been consistently good in the past suddenly all go down significantly in performance together. This is not normal. Many servers of the game went down before those strange things started to happen, which indicates that it is likely that those anomalies are related to whatever changes made in and around that down period.
