Recently I've been having some problems with a mod on Steam. Yesterday the author asked if I had the latest version. I thought, "Uh? I thought Steam automatically updated subscribed mods?" Then I went to my subscribed section. Yep, still subscribed. But when I clicked on the mod in question I found the mod's page showed the green subscribe button??? Then I checked all my other subscribed mods only to find that their pages also showed the green subscribe buttons! What goes? My subscribe page says they're all subscribed but their pages show subscribe buttons? Has Steam started a manual update system, or is there something wrong with my computer?

I had that happen too, though I can't say I've played enough to notice whether I've had any issues as a result.
