I've completed all the locations and the achievement is not given to me.

Looking throw the internet I found that there was a problem, like two years ago, that if you completed something with Aya you can't get the achievement. (Bug)

I review all the locations, in case I missed something. Also looked different videos searching for a tricky location, but they are all done.

Can I get the achievement in case that I've completed something with Aya? If the answer is "Yes", how can I get it?

There's an ultra difficult location that I can't find? In that case, help me!

It's the only achievement I'm missing, please, help!

PD: I think it's the correct place to post-it, if not move it please.
