unassigned resource added on xer import
I need to move several projects from one database to another. I created 1 XER of 10 projects. For the import I changed the setting to "ignore this project" for 9 of the projects so I could import just one. After the import I noticed a resource was added that was not assigned to any activity in that project. I deleted the resource and the project. I then created an xer of just that project and did another import. This time the resource was not added. Why was the resource added on the first import?
