I am creating a multi-page In Design document. One spread has disappeared. I cannot delete the pages. I cannot do anything on the pages. The objects on the pages seem to still be there/somewhere - they still appear on the Links panel which indicates their page number with a "P" in front of it. I have exported to an IDML file and the objects appeared, but want to know if my original document can be helped. When I select all - a miniscule box appears in the center of the spread, but I cannot get it to respond to anything. Does this have something to do with bounding boxes? Can my file, or the spread be reset to appear again somehow?
This is a bug in ID where the bounding box geometry somehow becomes corrupt. The best way to deal with it is to delete the objects, then the pages, and replace. Personally, I would use the IDML version.
