Well I can't say for certain that doesn't happen, and I have encountered a few glitches of my own in the game, but for the photo challenges I didn't have a single problem with people disappearing or whatnot.
For that particular "woman enjoying the water" one, she's in a very weird place, so you could've just missed her.She's in one of the moats carrying the water, near a grate.
I'll take another look, but I feel like I've already looked at all of those.
There's one moat beside that promenade overlooking the pool, one canal that spills into another canal with a waterfall-like feature, and one canal that connects the underside of two island sections that I remember; there might be one or two other canals as well.
I don't have access to that area anymore, and I'm not sure I'll be able to go back without starting another playthrough.
