63/63 locations with 100% Planet Progress but achievement is not unlocking. I’ve gone back to the planet and revisited all locations solo in case being in co op affected it. I did unlock Master of All You Survey already for discovering all named locations.
I’m in the same boat as you man. Did you manage to get it fixed?
No fix yet. I reached out to 2k Support and they said they have made the developers aware. We’ll just have to hope it gets fixed in a future patch.
You ever get yours because it is now doing it to me I have all locations discovered didn’t get achievement but my friend did and we play together.
