Yeah, I think people look at that criticism and think I mean I want super explicit bright glowing objects with a Skyrim style HUD that points me directly to where I need to go to get blue prints. Nah. Some ideas:

1. Some way to tell if there aren't any more in an area so you don't waste time looking when there isn't anything.
2. Some sort of device that tells you how close some are, but not where they are. Like the classic "beep ... beep ... beep beep beep BEEPBEEPBEEPBPBPBBPBP" thing that gets more frequent as you approach. But make the max range relatively small.
3. I think they were called life pods? Like the other crashed emergency escape pods. For things you're expected to get like the sea bike (I don't remember the name), sea moth, and moon well maybe always put some blue print fragments on life pods you find later. This way you can't miss them (unless you're really really not paying attention). You can still make it so you get them earlier on, but this way in case you missed some somehow you can always "catch up" to where the devs expect you to be. Like if they expect you to get them ~10% in, then make it so the life pods you find ~25% in give you what you are missing for the sea moth.
4. A bit of a map system. This one is controversial, so I'm putting it last. A huge appeal of the game is not having a map. But even just a blank screen showing you all your way points, but not showing you where you are or what biomes are around would be useful. Then do something like show where blueprints are in an area. Maybe something like once you get two of three it shows you the general area where the remaining ones are, but doesn't put a marker on the HUD.

Because with games like this where progression isn't gated behind actually having some of these items, you can get in weird states where you get further in and didn't get them. But maybe >95% of players did. The other <5% just missed something somehow. And then there's no real clue on where to.go to back track to get it. And you can get in these annoying situations where it seems like you should have it but you aren't sure, and you don't want spoilers so you don't look it up. Then when you look it up maybe you see a spoiler and it turns out you shouldn't have it yet, that's common. Other times you missed something super obvious in some very random area you only needed to go to once and never checked again because it seemed empty.

But it's just so infuriating when people say things like "you're not playing right" like, I'm getting frustrated because I'm playing right! If I wasn't checking everywhere I could miss things. So I have to check everywhere to make sure I don't. But then you can still miss things because there's no real way to guarantee if you actually checked everything.
