steam acting weird?

I had 0 recent game activity when I logged in around an hour ago, but everything is back to normal now. It's just another steam glitch, nothing to worry about.

i had same problem too, maybe something happening. :D

Today it removed my inventory, then in some minutes I got it back.

I tried putting some stuffs into my cart and sometimes they magically disappear!

One of the bonuses of actually owning physical copies of your games and what not.
You don't have to fear the entire library being taken away, crashing, and/or the company going out of business and taking away your games without telling you...
