Steps to repro:

3. Clear GI cache.
4. Close Unity.
5. Start a new Unity instance and create a new project.
6. Close Unity.
7. Copy over the entire Assets folder from the repro project to the newly created empty project.
8. Open the newly created empty project and let everything import.


1. Load attached project.
2. Run REPRO/Bake menu item
3. Close Unity.
4. Delete Library\metadata files
5. Load project again.

Expected result:
Bake data copied from another project is consistent with initially baked one.
