Quest appearing as not started

........

 

I think you have to re-do the quest since there are changes that has been made into them such as that Rune Mysteries quest wherein completing them now will get you a title which are either Red, Green, Grey and Blue. In addition, you can also obtain a tower helmet.

 

I think the quests are optional to finish now, you shouldn't have a change in your QP, they will just be unmarked because they have been updated since you done them.

 

Like the first guy said you have to recomplete them as they have been changed/updated by jagex.

You won't be able to claim any additional quest points though : (

 

Your quest points are the same still, but the quest has been updated and just be done again for the completionist cape.

 

I had this same problem for death platue, if there is an item reward from the quest, I believe you may have to re-do it, I could be wrong.

 

Jagex has started redoing quests, quite unfortunate, if I do say so myself.

 

Maybe you're confusing it for another account? But, since many people above me are posting of problems alike; I'd expect it just to be another glitch.
