Animation retargeting doesn't work

In 4.8 I tried to retarget animations from Anim Starter Pack to new default character.
Create rigs, for both, right click on animation and selected Retarget Anim Assets.

In new window I selected the new default character as target.

I looked like animation has been retargeted, but then I click on retargeted animation and it doesn’t work. There is no animation playing at all.

On the side note, should it be possible to simply retarget animation using source ? Skeletons are pretty much identical,
But for some reason I can’t select, from sample pack for the default character as source.

Edited: I haved used version from GitHub with latest changes from Monday.

Hey iniside,

The new Mannequin has a different base pose, among some other key differences. There will be an update to the Anim Starter Pack and a few other packs once 4.8.0 is released.
