I rely heavily on the "just in collumn to advertise my comic updates, it provides most of my views and keeps my rank strong, but recently it just isnt working.

Plz help me

Off the top of my head, there are a couple of reasons why you might not see your updated comic in there.
1. Does the genre etc, match your display preferences for thumbnails on the front page?
2. What time are you updating your comic? If it's close to 12:00am drunk duck time (but not after), then it will only display untill the clock gets to 12:00 am.

That happened to me once. Try changing your comic picture. It worked for me.
