Hey guys.

Something really strange happened to me and I have no idea how to solve it.
I seem to have lost the history of my curves permenantely.
For example: I create 2 simple CV curves and mage a loft between them.
Now, I play with the original curves and change them but nothing happens to the surface itself! as if the curves are completely disconnected from it...
What is wrong here? please advice and help me solve this irritating problem cause I can't work like this

Thank you all in advance!
