Not being able to interact with the campfires you find in the world. Huge let down.
Yeah, I know there are mods like this

Which usable unlit campfires seems to solve some of the issue.
But the swap all campfires mod just extinguishes already lit campfires for you to light them again. Which just makes me not want to use the skills of the wild, a mod that really excited me when I first saw it.
Skyrim is full of lit campfires with NPCs camping around them. I'd have really liked a mod that didn't touch them and made them so you are able to access the campfire system from them. Otherwise, it's very unimmersive and tedious for me to always build an unnecessary campfire to access a skill tree.
