@Boz - I understand that others have brought up the issue and made suggestions. But your comment makes it feel like you didn't actually read the suggestions.
All three address time-sensitivity in their own way. The "minimum" suggestion just provides a heads up, but the explanation point on the camp icon provides no promise about safety. It doesn't solve the peace of mind issue with Long Resting or provide any pacing guidance. Just awareness that content is being missed. Still useful though. The other two suggestions are basically asking Larian to take a stance (with code support). When the explanation point appears, resting should effectively have no impact on game time. IE: Resting at that point would be the same as going to camp and returning without actually resting. Whether they would actually allow people to long rest or would only allow a free Partial Rest is a matter of debate. The way I see it, Partial Rest is their invention anyway, so why not expand its use to solve this problem and provide some ease of mind.
