No stats info after round ends

[Mouthpiece]

I have been on a 2 month vacation off from PR. And now I come back and have this weird problem: after round ends, the info board about statistics (kills, deaths, points) is empty. And I can't manipulate it - can't switch to "best squad" section with the usual click of mouse button.

What could cause this problem? And how to get rid of it? Any ideas?

EDIT: Really strange, today it was the same in one map, but in the second (after server restart) it was fine - no more problem. We'll see how it goes tomorrow (or the day when I'll play PR).
