Yes, Mine had rough looking and feeling scales after a near perfect shed. I kept a close eye on her. Then just last night , the shed after that one her scales came back to normal and she looked great. I guess I would have to ask if there are any "sharpish" things that yours could have rubbed against to possibly cause this? Also in worse cases mites could have got under the scales so I might check for them as well.
I guess without seeing the "rough" spots its hard to say..
best of luck
