Media attachments not exporting with WXR file
I am attempting to export a Wordpress WXR file of ads from a Classipress site and then import them directly into another Classipress install (on a Multisite network). The Ad custom post type contents exports just fine. Custom fields, title, etc all look great, but the photo/media attachment doesn't appear to export.
Anyone seen this happen before? What is the recommended approach to export the entire ad, including the attached media?
