Timeline Override Layer gives Character in UMotion extreme offset

When "Syncing" a Timeline clip with UMotion that is on an override layer, the character will be completely offset, sometimes to the other side of the map. 

The workaround for now is to temporarily put the clip on the main Animation Track and put it back later after edits.

This could still be a problem with complex/multiple override layers, the workaround then would be a "fix-for-all" solution recording the bone data into a separate animation clip for on the main track and continue your work with that.
