Last night i with a pickup grp doing this mission (got it from Norrath mission keeper). sorry forgot the name (i'll check it later), but i heard it is must for next quest progress so we try to finish it. There are many steps from this mission. well,when we got the 5th step, we must find a note from Nethran ( a mob name),but ... my group clean all zone mob (right,all zone) and no any named up ...... Does anyone meet same problem as me? or do i lose any key step???

Thanks for your reply :)

Sounds like one my group did. Although I don't remember the name of the mission it might have been the one to find the perfect cherry blossom. In that case there is a room with a round pool in it. The mob we were looking for jumped out of there when one of us jumped in the pool.

thanks for tips! i'll redo it again

Missions, especially progression have been very buggy since last patch.

Out of 4 attempts at the Warlord mission last night, 3 spawned the wrong mob and we had to do over.

With a group of all level 70 on the mission where you gather the 3 drops and a container to combine them, half way throug it decided our level range was too far apart and booted us

We did this mission last night and it worked fine. Theres a room with a steaming pool in it, close to the end guy I think, near the step before Nethran. Theres a trap in the room, walking over or near the pool spawns Nethran and 2 adds, so be careful.
As for progression, I dont think you need to do this to progress, just the raid.
