I'm not sure if it's only due to high ping or if there are more variables at play. It happend twice. Everything suddenly stopped in place. There were animations, I could look around and I could hear some audio. One time it happend at the end of the game, the survey popped but the game didn't end. I tried to do some quick internet restart and only then it showed the final stat screen. So it seems like the game stops updating properly, with only audio going through.
