As the title says, I think the times for last post/thread created are off?
I remember waking up this morning and seeing a reply to some thread posted by Casey, at that time it was only a few hours old. Currently it's listed as being > 2 days old, but that amount of time hasn't passed yet...
Might have to do with the new style?
Well, your post clearly says '1 minute ago', so I think the functionality is fine.
Did you see this on the main page? Because the criteria with which posts are selected for display may have changed, so first you saw a recent reply to that thread and now you saw another reply to the same thread that's older?
Are you positive it was the same exact reply?
