Quest Kings

Wait, so this means that any repeatable quest, once it's again 'available' for completion, is taken off your quest list and your numbers go down? So things like BMM quest, The Sleepywood "DANGER" missions, Shumi's JQ, The Lost Guard, and of course the bounty hunter missions.... all of them are taken off your tally once they're available? So I guess in one day, you're tasked to tour the world of Maple Story and complete all of these in order to gain the highest quest total possible?

I wish I was home right now to check Maple, and I could see if it's dependent on if you've gone and activated the repeatable quest again... I'm assuming that's the case, but I still would like my dramatically stated question above answered

No, that's not how it works... The only quest which does what you just said there is the Cupid's Courier quest in Amoria. All the others have a "repeatable" mark in the completed section of the quest log (It's a yellow !) but they don't go back to available. The only way you could possibly get this quest to go into the completed section permanently is if you did it on the day of your 4th job advancement. The 24 hour repeat time makes it stay in the completed section for that duration, and the Cupid's Courier quest isn't available to 4th job classes, so if you do it directly before making the advancement it will never get the opportunity to return to available and should, thus, be stuck in completed. That's just a theory though, as I haven't had the opportunity to test it. :p

If you DO, however, go and and start a repeatable quest (say Blue Mushmom's) and then fail to complete it again (There are no blue mushmoms to be found, for example), and forfeit it, it will head back into your available list. This is easily remedied by logging off and it will revert back to completed after a period of time has passed in game.
