That is what most of us were complaining about. Some quests have time limits on them and some do not. I actually did not follow any set pattern, and went about taking care of everything I could handle in Amn, then leaving the city borders to take on Nalia's quest. Then I went to the halfling town, and then to the Red Dragon stage in the ruins...then I went to the grove...But I don't think it mattered where I went first...Although since I was a Ranger, and had my little town to protect, whenever someone came running up to me begging help, I went immediatley...I did not want to risk losing my reputation there. Then I would continue on with whatever. I hope this helps!!
