I can’t finish the Sinai Quest because I missed the picture at the lake. I saw it but now it is gone. Anyway to redo that part of the quest or should I just stop trying?

 

 

 

 

 

 

Thanks for reading. As in your second screen shoot, I was there but the picture taht I needed to investigate wasn’t. So now I can’t complete the quest because I didn’t have the picture. When I go to the next place, Izelle isn’t there either.

The screenshot is literally all it shows you when you run the quest in live time. It's just a blurry pic of the woman.
The following text is the clue.
You should still have the quest in your quest list, unless it got cancelled, and if that is the case- look under stories and you will be able to reopen the Siani side story and quest.
I think the whole thing is 5 parts, and most of them were pretty puzzling. I had to work with my bloodkin to figure it out and I much as I wanted to solve it all on my own, in the end I did refer to the YouTube video series I linked earlier to complete it.
Msg me in game if you have more questions, I saved the links.
