Re: Rope swings not reachable.
Uh.... This might sound stupid, but do you mean you cannot pull the ropes towards you with Force Pull or you cannot grab them with your hands while jumping towards them (not using force pull)?
Just in case (sorry) the ropes turn blue once they are in range of your force pull. If you press and hold force pull (don't know what key or mouse button that is on PC) when a rope is highlighted blue, it should be pulled towards you until you grab on. Once you have grabbed on and are swinging, you don't have to hold force pull anymore.
If you're just jumping towards a rope without force pull, you have to be very close to it to grab on to it.
If either of those doesn't work, then I'm afraid you're at the mercy of the devs and a patch.
Also, when you hold a rope while still having your feet on the ground, one that you pulled towards you with Force Pull, I always keep holding force pull and don't jump when going over the edge, there is some way the character let's go (I think it's the jumping).
I always try to jump first, be in the air, then pull the rope to me.
