Problems cropping a clipping mask to get pattern swatch
I'm trying to create a swatch of a repeating pattern that I created. Usually, I create a clipping mask of the repeat square, make a copy, crop any parts of the image that fall outside of the square and then drag the cropped square into my swatches. This time, however, as soon as I hit "crop", some the detail of my image disappears. I cannot for the life of me figure out why and I've never had this problem. Can anyone help? Below are pictures of what I'm talking about. Thank you!
