Frustrating little bugger that I finally nailed down reproduction steps for:
Reproduction Steps
1. Start a New Unity Project, do not import any packages
- Notice that in the title bar there is no asterisk (scene is not dirty)
2. Play the empty scene
- Notice that there is an asterisk, somehow the scene is dirty
3. Stop the scene
- Notice that the asterisk disappears
4. Import the PlayMaker 1.1 package
5. Play the empty scene then stop
- Notice the asterisk still disappears
6. PlayMaker > Open PlayMaker FSM Editor
7. Play the empty scene then stop
Expected Behavior
The asterisk should disappear
Actual Behavior
The asterisk stays!
Note: If you close the PlayMaker FSM Editor, the behavior goes back to normal.
