[PC][Classic]NPCs won't sleep or shut up about the sun

I thought I was okay at modding, but I think I might've done something to screw up this time.

After starting a new playthrough this year, I went through Dawnguard and joined the vampire faction. This was a while ago so I can't remember, but sometime between Harkon turning me and getting the chalice, everyone acts as if the sun has been put out with Auriel's bow. The sky is totally fine. Blue with fluffy white clouds on a good day, stormy grey when it's rainy, but the sun is still shining. I'm still quests away from doing the one where I go to the place to get the bow. Yet, even souls in the Soul Cairn gasp in horror at the sunless sky in a very un-ghostly voice and it breaks my immersion like crazy. It's getting really annoying, fast.

The second? It's hard finding victims as a vampire because nobody goes to bloody sleep. When I watch someone do their schedule, every time they're meant to go to bed, they just stand by the bed and never get into it. This feels like some cruel irony for deciding to be a vampire this time :/

I think a few culprits/victims in my mod list could be: Relationship Dialogue Overhaul, Sleep Tight, Immersive Citizens. Or maybe I did the bashed patch or merge patch wrong (I'm pretty sure I only bashed leveled lists together though, and the only things I touched in TES5Edit were item or NPC names/descriptions/stats)
