Nash, send a report to Nordeus, telling them what is happening and ask them to investigate if something has gone wrong due to the recent changes made to this game. Tell them about the ratings of the defenders and that it seems that defenders are not working like they should or attackers seem to past through them way to easily and score, what you observed, the excessive sudden amount to goals conceded, and so on. Also, included an image showing both of those matches.
Also, create a thread in the bugs section of this forum, and post all what happened to you concerning this, and include images.
I got this sort of anomaly situation again today. I already sent a report to Nordeus before this one occured. The more users that report, the better it is.
