Have a link with 4 joints (2 fixed + 2 revolute), all the joint coord systems & the link coordinate systems have the same orientation, with Z being the axis of rotation.
When using Load Transfer the Forces all balance as expected, but the moments do not. Upon closer inspection it seems the moments are not given in any coordinate system we have defined nor the WCS. It actually seems like the joint coords have been used, but the Y & Z axis have been swapped as the Y-moments are 0, but this may just be a coincidenc due to our link orientation.
Using markers seems to solve the problem, but would be nice to use Load Transfer.
