Hello,
Im using maya 2014 on iMac 10.9.1 making an A6M2 airplane.
Now Im making UVs (soo boring) but every now and then I get this error:

Its like if the UV has frozen on the object!!
I usually use a planar mapping or automatic mapping and then cut and saw…
Any suggesting to fix this and why its happening?
Thank you.
Edit: I just figure out the Mesh had more then one UV set!
