NPC Spawn Issue: Highkeep Bards & Nobles

[dojo420]

the spawn time on "a noble" in HK appears to be much longer (23 mins ) than on live (6 mins).

When about 3 minutes have passed, kill the remaining noble. Once this noble is dead, the room is split and you are ready to take the bards the same way. The bards spawn much less frequently, so they are easier to camp

Source

Nobles are on a 6 minute timer.
Isabella is on a 6 minute timer.
Bards are on the same spawn timer as the guards - 18 minutes. Use the noble spawns to keep track, 3 noble spawns to every 1 bard.

The bards seem to spawn correctly but use their charm spell which i dont remember from live myself (same with the bard in nk at the well). don't have any sources on that though if anybody else can help out...

Thanks
