I am creating a pattern and have drawn the flowers as vectors. When I go to save the finished pattern some layers are missing when I reopen the file. I think I have too many layers/ curves? When I open in photoshop I have 7999 layers. As you can see in the first image every flower is made up of lots of layers, is there a way to flatten each flower into one layer while keeping it vector (I do not want to rasterise as I want to be able to resize). I have tried to merge some curves together, but when I save and reopen it looks like the last 2 images, when lines overlap it has gone transparent?? Help.
