got into a snow shelter in FM (near a spawn point) ( so I don't give away the location as a spoiler.) anyhow, right after entry I can see out, and see the campfire and use it but I cannot exit. the option never comes up and the view is different than the standard snow shelter view. I needed to sleep, have it save, then go back to the game and the view changed, I could exit the snow shelter. easily repeatable as well.
