Ah. I see your point. While it does suck if the rope is lost, I would personally rather lose the rope than go from level 1-10 Carpentry after getting 6 ropes and 12 planks without ever leaving a safe area (I.e. second floor with stairs sledgehammered out). This issue, to me at least, makes survival a bit too easy due to how strong you can make your fortifications in such a short span of time (not to mention the crafting benifits). While there may not be a perfect solution, I'd rather sacrifice the rope over making the game too easy to survive in. However that a just me. As far as I'm concerned, I never pack or unpack planks unless I am building a major project such as a new floor on my base or whatnot. It is an avoidable exploit for those who don't build as much, but a game breaking one as well for those that focus carpentry (like myself) imo.
