I allied myself with Furrante and had the help of the dragon as well, so the dragon can indeed be the source of the problem. The thing is, I don't want to change my approach just because the fight is bugged, because that's kind of ruining my immersion if I'm forced to do something not the way I like it just to get past a bug. Hope it will be fixed soon and if so, would someone be so kind to let us know about the fix? Wouldn't want to go through the whole storm part everytime just to see if the guardian is back.

I'm having the same exact problem. The Guardian of Ukaizo marker is placed in the same place as in the screenshoot of DrHollywood and spawns and de-spawns of enemies occur in the same way the author of this topic described. Seeing that I can't find any mention of this bug before, I'd suspect it has something to do with latest patch. Don't know about DrHollywood but I have Beast of Winter already installed and finished it before proceeding to Ukaizo, don't know if it matters though. Hope you'll be able to fix that bug soon, because I'm not sure whether I should proceed forward with this bug or not, as I don't know whether it can have any impact on save game (considering that it happens in the very ending) and possible future exporting of this save to hypothetical "PoE III".
