I think I experienced a similar thing. I wasn’t really paying attention to the match but when I looked at my screen in 3 minutes after starting the match, it was 77th min, I was up 1-0. Then it took another 2 mins or so before the match ended, scoring a m other 4 goals in last 10 match minutes. Then I checked the report, it showed nothing happening between 1-36 min and 45-76, but having yellow cards and 4 goals after 80. I’m sure they just messed up the match time counter for some reason.
As I side note, my last goal was a chip shot, which I have never seen before in T11. Looked cool except for the lagged jump of the GK
