Short description of error
This is not a bug but a missing UI element from 2.79
The option for Make Parent without Inverse is missing from the Ctrl+P menu, this results in confusion since the default parenting behavior is actually not standard in other 3D software and game engines.
I have spent hours today resolving this issue when exporting to an external game engine
Others have also been confused by this https://twitter.com/chadvernon/status/1101151577321029632
