Valve has some problem with math

This is not even new at all.

Idle more than 2 games at once and playtime will duplicate

Once Valve gave me 27h in one game, but in reality i had 2.7h, so they just removed the dot.

I though we all know that Valve can't even count to 3.

I have some problems with meth.

Obviously idling multiple games in the same time.
