camping and supplies sure do make the game more difficult and thrilling but it may cause certain "point of no return" if players weren't aware. it will be great if larian decide to do so, then make sure there's a non deletable auto saved games checkpoint.

if i may name a game, pathfinder kingmaker has a location where it's entirely possible that may screw up players upon entering the location and it's get locked and won't be able to return to the world map until that location is completed. that is on a normal difficulty by the way. you won't be able to get out of that location and with 0 camping supplies with all your characters exhausted and all depleted spells and talents.
