So the instance starts out as normal but whenever Garuda disappears for the first time my game still registers her as there. Rain of feathers comes down and Garuda vanishes, then minstral Shriek happens down the pillars. Garuda doesn't reappear. Plumes are summoned and there is no Garuda to target for 2nd phase.

I am on ps3 and my party can see her while I can't. This will happen 50% of the time. If it's an error on my end then I accept that but I've reset my router after each occurence to make sure that I'm at least making an effort to minimize any lag on my part.
