What is with the "Past 2 week playtime" gone buggy?

[Tian]

As this title says.

I just seriously noticed most of my games for the past 2 week playtime gone a thousand hours alerady , eventhough the last time i seen it's like from 1.0 to 70.0 hours in the last 2 weeks.

Eh , is Steam bugging the hours?

Yeah it's bugged and all my friends' has this problem and their friends too. Also stats for some games not working at all, like Left 4 Dead 1 which is not updating at all for several days now (the stuff how much games you played, how many zombies you killed etc), but it worked well before.

Report it to Steam Support. Launching a game for 5 minutes and the "Past 2 Weeks Playtime" goes up to +200hours for that particular game. Also it's clearly impossible to have 1000s of gameplay hours in two weeks. Something is wrong with this and as I see it's global issue on Steam, not just a few users.
