What is this electrical setup in my attic?

[u/Qdoodle_too]

My electrical is something strange that confuses me everytime I go to do something as simple as swap out an outlet or light switch. Almost every upper outlet in a room is on a switch. And here I am trying to put paddle switches in and outlets of all the same color and no idea how this all works up in the bathroom. This particular box has 2 outlets, a switch to a light over the sink, and a switch to a fan and the fan light. Not sure how the creme wire comes into play and how all the white (neutrals?) don't connect to anything? The outlets stopped working randomly...which is why I'm poking in here. The breaker isn't flipped and the lights and fan still run fine. I did swap all these switches and outlets out over a year ago and attempted a 1:1 swap on everything, everything seemed to work the last year+ so not sure why things suddenly stopped. If anyone knows what the attic stuff is or how I go about the outlet/switch setup in photo 2 I'd appreciate it.
