Strange issue with Promethea

So my planet progress for Promethea is 97%…I am missing 2 red chests, 1 Eridian writing and 2 crew challenges…however…every single zone I have 100% completion (except the one that has 101%) and I’ve completed the Cistern of slaughter, I also only count 12 red chests in those zones but the planet progress claims 15

What am I missing? (except for the City Slicker achievement not unlocking, I’m missing that also)

15 Red Chest is correct. You can use this interactive map if you missing anything in your game.

Yeah the penny just dropped, I had Lectra City missing from my navigation menu

Although, still at 43/43 locations and no City Slicker achievement
