Not that i've noticed. You want to be more specific? Are you on a TLP? Did you change the language you are using in game? Do you have the npc targeted when you speak the key quest words back to them to progress the quest? Are these one time only quests? Are you trying to Multi-quest stuff that has been fixed for that not to work? There are many, many reasons a given quest may not be working for you. You'll have to give us some more info. I'd recommend- What server you are on. Your character's class,race, level and relevant skills. The name of the quest you are trying to complete and the zone and npc it started with.
