The project file has been modified since last save. Do you wish to continue?
Suddenly this pop-up started to appear when I want to save my projects.
It is annoying.
And when you click OK it seems to save the project to your autosave folder. I had been opening my file from the 'recent projects' list when opening premiere. I just discovered this whole time it was saving to the autosave folder and my original file was now 10 days out of date.
