Among the Steam achievements that popped up as completed today (15 of 'em!) included several location based ones: A Hundred Names For Sand (Pandora), City Slicker (Promethea), Exoarchaeolo (Nekrotafeyo), Master of All You Survey (all locations in game).
The Bolt-Ons one unlocked too (buying cosmetics from Earl). I dunno if it makes a difference or not, but I had “pre-completed” the requirements for most if not all of these while playing on Epic, and they didn’t trigger as complete when I transferred my savs and profile over to Steam (was a known issue at the time.)
Now that I think of it, there’s still that persistent location bug in the game where you keep re-discovering locations over and over (and get XP awards for it) that was introduced a few patches ago. Maybe I was able to get those achievements knocked out because of my earlier Epic playthroughs where all the places were unlocked before that bug came into the picture.
