Unbelieveable lag

[chainlink]

Did an immo run last night (with max 10 people) and it all went fine until we got to the main man. After this the lag got worse and worse for everybody involved until we were all down to about 0.5 FPS. We only had a couple of casters and no AoEs up so I'm not sure what was happening but as soon as we killed him it was like a piece of elastic as the frame rate snapped back to normal for everybody. We only lost one person through lag death and Fugue which was quite impressive as I was the only immortal in the party bt I'd be interested to know if it was anything we did that caused this? I was playing with Elfin Gald login Arghh Swiftsword if that helps track the log down.

Did an Immo run with 7 players yesterday, we did a bit of testing (see reduce lag topic) and suffered no lag and caused no server lag.
All players on our run disabled the combat messages.

Believe me we really push the run to its limits (spawn 70% of each map, used storm of vengeance and had casters throwing spells).

Might have been pure luck on our part.

We had minimal lag with the mobs it was just when we got down to the immo fight that the problems started then vanished as soon as we killed him and it was instantaneous.
Alive and kicking - less than 1 FPS
Dead - 50+ FPS
