Short description of error
In 2.79 when you applied scale to objects and their parent empties it was applied to all of them at once. In 2.80 that has changed.
Exact steps for others to reproduce the error
Open blend file.
- There's a cube and an empty. Cube is parented to the empty. Each of them has a scale 0.6.
- Select both of them and apply scale. Only the empty will have a scale set to one.
- Select both of them and apply scale again. Now also cube has a scale set to one.
