So I decided to play through some of Half Life 2 today, mainly because the group/event that was planned gave me a good reason to do so (even if I thought their idea was rather silly). Anyways, I just saved and shut down the game, and as soon as I did, Half Life 2 starting updating. The update seemed small since downloaded rather quickly. I was wondering if anyone else noticed this or had any ideas on how to figure out what it was? Or maybe it was just an isolated incident?
