I noticed while sorting my steam games by achievement completion that a bunch of my INFRA achievements are missing (and only my INFRA achivements). It seems to be all achievements from my second playthrough where I was specifically achievement hunting. I visited Xeander Berg's hideout, won a jackpot, photographed spots, found caches, messed with the demon core, etc... I got all but one achievement at the time, and now that all seems to have been erased.
I tried redownloading the game and continuing from some old saves and got a couple of missing achievements back (Natural Selection, Party like it's 2011 and Night Shift). I could probably also get Truthseeker, Behind the Scenes, and Just Leave it to Me back the same way, but that still leaves a whole pile of missing achievements from earlier points in the game where I don't have saves.
