ID 458030 - Driven Action becomes un-selectable when scene file is reloaded

Follow

Problem summary
Driven Action becomes un-selectable when scene file is reloaded. If the scene is then re-saved, the file size will be much smaller than the original file.

Customer reported version

Steps to reproduce
1) Open Modo.
2) Select File > Open and open the provided repro scene.
3) Select the "Animate" Layout.
4) Select the dropdown to the right of "Actions" and select the action.
Result: The action will not be selected.
5) Select File > Save incremental.
6) Navigate to the saved file and inspect the file size.

Expected behaviour
Driven actions should remain selectable when a scene file is loaded. The re-saved file should remain similar to the original file.
