Activities which have had their activity ID changed cannot be updated correctly by the Update Baseline function.  The issue can be seen if the following steps are followed:

  1. Create a project with two activities, for example A1000 and A1010
  2. Create a baseline of the project (using the "Save a copy of the current project as a new baseline" option)
  3. Add a new activity to the current project, for example A1020
  4. Exchange the Activity IDs of the newly added activity, with one of the existing activities
    • For example, Change Activity A1000's ID to "Temp"
    • Then change Activity A1020's ID to A1000
    • Then change Activity Temp's ID to A1020
  5. Run update the baseline.
