It probably won't happen to an inflated wing because the strut bladder won't shift down--probably. There are a lot of ways to screw up the bladders since they are free to move inside the tubes of the strut and leading edge. Anything you do that promotes shifting, twisting, folding, or otherwise moving the bladder from the position it needs to be in and/or usually takes can cause big problems. I dry my wings at the beach, inflated, as much as happens between getting changed, putting away all the other gear, and then deflating and rolling up the wing. It's not a careful process, I'm a slob, I don't roll up the wings carefully, I fold them tip to tip, roll them together, and stuff them in the bag. Sometimes they smell like a long-dead muskrat, but I don't have trouble with bladders. I use one or two almost every day. People doing more occasional use might want to take a bit more time. But don't hang them from the handle.
I watch people doing a super-careful, tight roll of each wing before carefully folding them, putting a strap around them, and gently placing them into the bag. I wonder how the bladder does with that tight roll. Sometimes neatness is not the best prescription.
