So basically, the rope items (stuff where you put it down then set the end point, chains, midway lights, etc) don’t play well with movers. They can also be more difficult to work with, AND don’t scale.
Any chance to get static versions of these, maybe with pre-set length variations? This would open them open to be used on moving pieces, or even scaled up (like larger midway lights, or thicker chains), and just would require multiple of them to make longer ones.
