Significant bugs with copying or importing a project:
Copying a project -- task assignments are wiped -- WHY?
Usecase: I have a 300+ task project which is re-used periodically, with minor revisions. I want to copy the project to a new instance, so that I can keep the original for record. I loose all of the assignments. That is a major amount of re-work (and fraught with error) to have to manually reassign the tasks. What good reason could there be for trashing that data?
Importing a project from an .mpp file Task assignments AND task durations are wiped -- WHY?
Attempting to work around the above _BUG_, I exported my project to an .xlsx. All data is included. Upon importing into MS Project (desktop app) all data is still there. Export the project to .mpp. All data is still there. Import the .mpp to Project for web, assignments and durations are lost. WHY would you throw away important data that is included in the .mpp, and without even asking?
