Worked: Create the inputs at the node_tree level
Short description of error
bpy is letting create inputs at the node level for node groups that make blend file unsaveable by crashing blender saving.
Exact steps for others to reproduce the error
- Go to compositor view
- Create a group by adding a Mix node and then group it
- Execute this line in the python console
- the node now has a new input, but then entering the group the new input is not there
- save, here it crashes and it doesn't save the file.
The blend file is in step 2)
