Fire Island Bosses

Who here has noticed if they are haveing problems with the bosses in the Fire Islands?I was helping someone trying to cap Charge in Perdition rock and Balthazar's cursed was no where to be found and the same as the Ettin with Healing hands.I was wanting to cap Shield of Deflection in the RoF mission but the boss was not where it is suppose to be in front of the Musraat fort as I capped it there twice.I wonder if this has anything to do with the lastest update with problem in the Fire Island Missions?thanks.

if you look at the elite cap maps, you'll notice that the bosses can spawn at several locations randomly -- or not at all. Also some of them have very large patrol paths, and while they may spawn at one point, they may wander from that point significantly.

I had to zone into Perdition three times before the ettin monk boss spawned.

Thanks for the replies and yes they spawned and that Monk ettin boss was pain as this is my secound Monk.I was with henchies and the only was to go protection instead of healing or smiting.
