Linking object to animated model Machinima/Create

I could not figure out how to link an object to an animated actor in Create, so I went into Machinima and connected it via Constraints>Transform Constraints.
This worked to put a torch in an animated actors hand.
However- when the file is saved and moved back to Create, the animation works, but the torch does not follow along with the model, it does not move at all.

31 warnings and 19 Errors occur in Create upon opening.
Log File from Create after opening file…
