Fissure of Woe quest bugs

My guild regularly does Fissure of Woe, and we have had the time to really examine it. We find that there are a few problems that need to be resolved.

1. The opening quest, fortress, has been gettings stuck at 5 groups to kill. Our guild normally zones in, pulls the mobs to the S, then the mobs to the N. We clear to the point where the NPC usually runs to. Then we kill around the fortress. At that point we speak to the NPC to gain the quest, spawning the boss which we will. What has changed is that the NPC has stopped running up to the point which he normally does. Instead, all the mobs around the fortress despawn, and the NPC stays put even when you click the quest. That makes it impossible for you to kill those 5 groups, as well as cause the boss to spawn as the NPC isn't close enough to open the gate.

2. The weaponmaster quest can easily be "bugged." If you take any other quest at the same time, it will become bugged. If you kill the mobs on the road between the weaponmaster and the temple of war, you potentially can bug the quest.

Has anyone else experienced these problems, and do you have any work-arounds to get them to work? Or perhaps these are intended?

A response would be great

they aren't "bugged", just "not so good" made

for the last quest:
the last group is around outside the temple

1) The initial quest seems to have been fixed. A certain group triggers Rastigan's movements, and it seems as though the five groups have been fixed as well so some only spawn once someone takes the quest.

2) If you complete quests in order you won't have this problem. If *one* person accepts multiple quests then it seems to not work. Since that's apparently happening and people can't simply not touch the shiny quest button, I'd suggest just giving in and getting the extra 20k exp for the two quests prior. Darn. :P

Yes, it definately seems to have been fixed overnight

Was able to do 4 quests in FoW last night, no prob. Only thing that still gets me is some of the collision detection on the gate to the Temple of War.
