Notes:
- This bug case is closed as `won't fix` because the issue is from Unity 4.x where Autodesk's Beast lightmapping solution was used as baked backend. It is now deprecated and new backend solutions are used. If you encounter this type of issues in Enlighten or Progressive Lightmapper, please open a new bug case.

Steps for reproduction:

1: open the project and scene test1
2: Go to light mapping and bake scene
3: select ground
4: bake selected
5: notice changes in the shadow on the ground
6: bake scene again, to fix shadow
