Are they listed here: http://tw.dkpsystem.com/adminappreport.php (use the "Application" pull down if you have more than one type)

That page is accessed via the main menu, which you may have turned off or not thought to check. I just took a few minutes looking through my Admin options to find it myself.

(My guild has all apps automatically posted into the forums so we normally check there)

If they aren't there then that's something for Chops alright.

Also, what's the name of the app that went missing?

Found it ty, I did have it off, just moved it to a visible menu, ty
