Steps to reproduce:
1. Create a cube and attach another cube as a child
2. a) Set any scale of the child cube to 0.1 and duplicate it, the scale values will be corrupted
b)Set any scale of the parent cube to 0.999999 and duplicate the child, the child scale values will be corrupted

Expected: Upon duplication no values are changed, they match the original objects values
Actual: The scale values are changed slightly resulting in minor, but possibly important mismatches
