I never had that problem with a properly aligned cameras and film backs.
I used to be a believer in the phenomenon and even did my own tests (which confirmed it in a Yashica D and Rolleiflex automat!) but as I've begun conceptualizing a roll of 120 as something that is intended to last for one outing, not for a week, I don't see it as a real issue anymore. That said, if you let film sit on the rollers in an Automat for a week, it will get kinked and reduce sharpness in some parts of the image at large apertures.
Practically it's not a real issue unless you're shooting infinity landscapes wide open after leaving a half finished roll of film in it. But if you really want to insulate yourself against this phenomenon, you need a Mamiya TLR, an Autocord, a Pentax 67, a Koni Omega or one of the other rangefinders.
