[CLIENT] In-game friend's preview screen displaying incorrect game time

In the friend's list in the client, moving the mouse over an in-game contact sometimes displays the wrong in-game time, with past experiences showing times of above 60 minutes despite having the match just start.

Up until now, this has happened to individual friends, with other friends showing correct times (have not witnessed any occurrences with pre-made groups of friends displaying wrong times at all).

This seems to occur randomly, and I have not been able to reliably reproduce this bug.

I'm not sure if this has been previously reported; a few google searches shows something similar happening with the old client dating before 2012, but nothing of the sort past that.

See picture attached. My friend just went in-game (see chat).
