Quest pick up problem

OK this has been happening way too often recently, like every hour or some, sometimes even more often. The bot works and everything and then it just runs into a quest that i tries to pick up forever even though it has been either done or picked up already. Here's a log of it happening to me recently.

It doesn't matter if I use addons or not .

 

<TurnIn QuestName="To Conquest Hold, But Be Careful!" QuestId="12487" TurnInName="Conqueror Krenna" TurnInId="26860" />
<PickUp QuestName="The Conqueror's Task" GiverName="Conqueror Krenna" QuestId="12468" GiverId="26860" />

turn in that quest, press start
