While working on a master program I modified a sub-project. Chose to save the changes etc. I then opened the sub-project and noticed that the schedule was not at all what I had seen or saved in the master project.
Checked everything, and all looked ok. The Tasks were set to ‘Auto-schedule’ and Calculation was set to ON.
So, something to be wary about. If the scheduling seems odd, go for the F9 key. Obviously, there is a hidden baguette/issue in Project 2010.
BTW, the version is SP1 + June 2011 CU.
