Does anyone else have rope that just "die" and have to be ripped out and re built?

[Mulbin]

Its happened a couple of times now, a rope will just no longer have physics and I'm wasting a lot of time rebuilding them. Literally just becomes a pole, no gravity, not movement, no ability to alter length... like the backend code has somehow broken.

Is there some way to refresh a bugged rope or shall I rip it out again and rebuild?
