double surfaces

 From:  crydee
hello micheal,
i have a little problem. i created a car with moi. i have some trouble with one part. if i join the patches and then separate and join it again, everything is okay. if i reload the file and separate this part again i get all patches doubled?

maybe you can have a look at the attachment. you'll find the specific patches in the cyan layer. copy all the patches to another style, join them and save the file. reload it and separate the joined parts. et voila, all is doubled :(

it's strange. hope you can help me.

thanks in advance.
