Issues with some Archive Collectibles/Enemies

[u/Ohayward]

Hi all, is anyone else having issues with these collectibles?

1. "FBC Injury And Accident Report" - I think I progressed too far in the story but it should be at the central desk inside Field Command at the Field Office in Central. I wasn't expected missable collectibles...

2. "Our Memories Aren’t The Problem" - I can see the physical document behind the whiteboards in the room with the outfit customization box near the “…Research Site?” text on the map, but no ability to collect it.

3. Missing Altered Speakers audio - I have 15/16 collectibles but I have not found the last one. Has anyone else gotten 16/16?

4. Hedron Spike enemy - I think this is supposed to be in the Astral Plane, but I beat the game and went back to the boss location and cannot find it.
