So, here's a fun bug I ran into this morning.
I bookmarked today's comic thread, which was posted by Geth at 12:01am:http://forums.penny-arcade.com/discussion/184228/pa-comic-monday-october-28-2013-parabolic
When I go to My Bookmarks, this thread appears in the list and gets blue-flagged as normal when there are new posts, but the most-recent post is labeled incorrectly (on this page only) as having been made at 12:01am. Which pushes this thread down the page by the default Most Recent Post Sort Order.
Just a funny little glitch.
Here's a picture of the behavior on the Bookmarks page:
And a link to that post, which was from 9:27am, not 12:01am: http://forums.penny-arcade.com/discussion/comment/28270480/#Comment_28270480
