Pantone Color Changes to CMYK
When I have an object that has a pantone color associated with it but then the pantone swatch is deleted from the swatch panel, the object color changes to cmyk instead of keeping its pantone color. This is causing issues with printing, as it will print a different color than it is supposed to.

Jay, this is how it works in Illustrator.. If you have a spot color in a document, it should stay in swatches. When you delete it, it can no longer be present in a document and thus is converted. Just leave swatches you use.
