"Not having nights is not a problem to immersion because nights happen when you sleep and can't see them" is a pretty fucking terrible argument. especially in an a game about traveling during a long adventure and crossing dangerous territories and creatures.
Personally, I could get behind this design, though at the moment it is undermined by the issue of camping not happening/feeling connected to world map. "We decided that you travel during day, and rest at night" is a fine design - there is of course potential in being able to travel at night, but not many games actually live up to the potential. But the transition between adventuring and resting just doesn't feel good.
I don't think the following would work but, what if there was some time limited that would force us to go to sleep? It could be time based, or like in disco elysium, activity based. Something to make the it feel lke the the world is not completely static.
