Yesterday, I had the same issue like your and only problem in friendly match like you have said. This is my second time since the update. Last time was like a month ago and happened for couple days, then it went back to normal. I don't know how long this one last, I will find it out after my league match.

One thing I have noticed though, a day or two before, I used all 23 players in a friendly match. Have you sub all of your reverse players prior to the issue?
