Achievement bug?

[Frame]

I have scoured the map and I believe I've collected all the pocket bags for the "Pack Rat" achievement, but it hasn't unlocked. I have gotten the "Cleihrophobisdt" (opening all vents and doors) before I had opened all of them (specifically I was missing the two vents in the Soldiers Quarters area of the map.

Has this happened to anyone else?

I think I'm in the same boat on the Pack Rat achievement. I'm on normal difficulty and have 12 inventory slots unlocked (and I checked where every pouch should be and found nothing). Any ideas?

Further playtesting is needed to confirm or deny any of this.

I encountered none of this.

Pretty sure you're supposed to have 13 slots to unlock the achievement.

I have 13 item slots but haven't gotten the achievement, not sure what to do from here.

I got it by playing Easy Mode. You actually fill up all the slots in your inventory screen on Easy Mode because you start off with more slots. The number of pockets you can obtain is still the same.

There might be something wrong with the achievement on difficulties that aren't on easy. But also don't forget that the spawns can be random

Like sidneyc1990 said, in easy mode you have more inventory slots than on normal and hard. Maybe the requirements for the achievement is set to 14 instead of 13, making it impossible to get it on any other difficulty that isn't easy

I also had some issues with the achievement but got it once I played through the game again on easy

I'd suggest try running through the game on easy and collect all the bags. If you get the achievement that should be evidence enough for my theory
