Steam Explorer Achievement Not Granting (solved)

[Maira]

I've gotten every form, life egg, pet, song, and treasure, including the 3rd cooking slot and all 3 memories for the secret ending. I've even got the Weird Fish achievement. Somehow I still don't have the Explorer achievement despite beating the game, and I haven't got a clue what I could be missing. I don't suppose there's a way to fix this?

(This is actually my 4th time I've played the game, I just wanted to get the achievements on Steam because Aquaria is my favorite game.)

Oookay, so I was missing a tiny area, a save point in the Energy Temple. Since this is a frustrating issue, if anyone else is missing one small thing and can't get the Explorer achievement on Steam, see if you missed any of these. I also included my own 100% completion file if nothing else works.
