By the way, just checked my previous games from the start of the season. Before the update I played against narrow diamond with my V-style 5 times both in league and cup. The opponents were much stronger than my yesterday's opponent and all were active (except certainly the league match against the same opponent as in the cup). The results are as below:

6-0
1-5
6-0
6-0
6-0

And then after the update I suddenly get a loss 3-4 - that is not a coincidence(((
