Are these new-ish leaves? The reason I ask is that new leaves usually have a rubbery feel to them. That's the only thing I can think of. I don't know where the wrinkled part comes in though. Do you have a close-up picture of the wrinkled leaves?

No, all of these are older leaves (but not dead/dying leaves). I don't have a pic of the leaves up close but honestly, there really wouldn't be much to see. They look almost normal. Somebody on another forum suggested that there might be a near break in the vine , so I am gonna check it out and see if I see any damage. I will try to post a pic of the plant tomorrow if I can-

Your description made me think of newer leaves, too. They always start out less succulent, very pliable (or rubbery) and darker green. They stay this way for me for a few months before starting to stiffen and thicken. If they're wrinkled, that's usually a sign of underwatering and you'll notice it first on the newest leaves.

Could the roots of those particular vines died off for some reason? It sounds like the vine is dehydrated so root rot could be the cause.

I just chopped up the vines last night and I'm going to attempt to root them. I can't figure out what is wrong with them- some of them have 2 vines growing out of the same base, and only one of the 2 has rubbery leaves..... weird. Anyway- we'll see if I can get the cuttings to root-wish me luck, I usually can't get the dang things to root!!!!

Are these vines bare? In my experience bare vines won't root. I let them grow a minimum of one node more (w/ a pair of leaves), then root them in mix or water, depending on what it is (I've done Obovota cuttings both ways).
