We STILL seem to have a RANDOM ARCHIVE GLITCH where clicking on the next comic will take you to the next comic page, but oddly display a comic from a totally different date. Hitting Refresh sometimes helps. We're working on it!
Comic for Monday 09/30/13
Ref: Perhaps this?
Also Head's-UP: New Comics Mondays Wednesdays and Fridays for this month and possibly the first half of next, and then back to weekday comics!
