Session cookies not refreshing?

Seems that the session cookies aren't refreshing properly (rather, the session doesn't seem tracked, it seems like the initial login is and then "times out" after a certain time). Here's a rather interesting screen shot from the Addict's Forum (with all pseudo-useful info blurred) that shows me reading it, but that I'm not logged in (ie. I can't assign points to Terr "because he's been banned" - which is clearly pretty laughable).

I know this has been brought up several times... just hope this helps lend some sense (?) to it.

Keep up the great work JP!
