Hinge rotators and spring shaft connections

I have a vehicle with a custom suspension;

The vehicle has four sets of suspensions, using two springs for each set. I used to have it so that a hinge rotator connected to the spring, which then connected to another hinge rotator. The connection went as followed; vehicle > hinge base > hinge shaft > spring base > hinge shaft > hinge base > wheel bar.

Since the last patch it is no longer supported to connect a spring shaft to a hinge rotator shaft. I tried solving this by flipping the last hinge rotator and connecting its base to the spring shaft instead of shaft to shaft. This atleast let me launch the vehicle, but the spring strength seems to have reduced to pretty much zero (even when upping it to 2000%)
