Ooh right it is currently raycasting, I'll change it so that whenever it's in the box collider only then you can pick and drop the paper, that would fix the issue ig.

That if a code letter is currently open, don't matter where are you now, you can close it. In your solution (box collider) may happen same thing as before. Example:
- I pressed S button (go backwards)
- And on last moment I open letter
- My position got updated (from 1st step)
- And now I'm outside of collider
It may happen rarely, but I was lucky to see that :)
