Hey DigitalClay,
This has been fixed. When you pull up Project Browser and select New Project, there will be a down arrow in lower right part of window. Click that to select where you are saving project. I have tested this with DropBox, and it saves to DropBox folder without any issues, and Levels save just fine. Do you see arrow in Project Browser > New Project?
If you are collaborating with others, you might want to look into some source control software, too. It helps when working on same project with multiple people across multiple systems.
Hope that helps! Let me know if you don’t see that down arrow to save your project in destination of your choice.
