*Steps to reproduce:*
# Open attached project.
# Open scene "SampleScene"
# In Project window,select Assets > PlapaBush01 to view in Inspector.
# Click "Open Sprite Editor" in Inspector.

# Change the value of "Outline Detail" in the Outline Tool, and click "Generate".
# Click "Apply" in the Sprite Editor and confirm again with the pop up.
# *Restart the project and repeat Steps 1 -> 6.*

*Actual results:* The second time you do this, the sprites will be blocked out in black. It may happen the first time if you have opened the project before.

*Expected results:* Same as the first time you complete the steps, nothing unexpected occurs.
