Steps to reproduce:

• Create a 3D project
• Create an effect file
• Double click the effect file in Assets view
• Create effect with Effect Maker -> Save -> Export
• -> Would expect that Effect icon in Assets updates to this:
•  
• -> Icon does not update and shows the "not ready to use" version.
• -> Saving the project seems to update the icon, but if no other changes are made at this point, File -> Save All is disabled
