This is a recommendation. I think that resting in camp should be unaccesible when you are underground in a cript or dungeon quest.

It is a bit strange and it brokes the narrative.

The party should do a long rest into the dungeon or cript. One thing I appreciated of first Baldurs was when you tried to rest in a dungeon and some enemies could broke this action.

In any case, this kind of rest right now seems weird stuf.

I'm enjoying a lot the game.
