Client: Friends list not updating properly. Wrong status and wrong in-game time!

This bug has been in the client for ages. Idk what is Riot waiting for to fix this but here we go again.

Both of my friends are actually offline, at the moment the screenshot was taken. Yet, the client still thinks that they're connected : one in game and one AFK.

Also, the client shows the wrong in-game time when friends are done with their games and they're still online, or just disconnected after finishing a game. You'll see times either like a " -:- " or like " 80:53 " and such.

So, Riot, would you, please, fix this already so that the client updates players' status, and in-game timers, properly?!
