Treasure gone before I found it?

I got the ‘sketched map’ from the cottage north of Annesburg and made my way to the hill above the Elysian pool to collect the treasure. I was hoping this would be a quick win. 

But when I got there and looked behind the right stone, all I saw was a hole in the ground and no option to search. 

I got this treasure fine in my previous play through, and I’m pretty sure that you can’t find a treasure with having the map first, so where the heck is it? Does it take a while to spawn the treasure for some reason?

Haven't done a treasure in a while but when i did, it was bugged a few times. I've had similar situations. What i did was moving on. I've returned a day later and then it was there. For me it was simply a spawn bug.

Yes, that’s when I’m hoping. Not that I mind too much, there’s enough treasure around to get the explorer challenge without it.
