Deformations are wrong when you change deformations, export the model, import it again. Now the
deformation from the second in the deformation chain up are wrong unless you change them in the reverse order of the chain.
The deformation is even wrong with a non-exported/imported model when you don't make changes in the chains reversed order.
This makes it impossible to use a deformation chain where the model keeps its form unless it are two hinges that remain parallel.
See the link below for further information and illustration of the problem.
