Rigid Core not working

I have been working in a parametric diagrid structure system for tall buildings and i can’t make the rigid core work. Although no mistakes appear in karamba, i mean all components run normally, i can even delete parts of the core structure and the results wouldn’t even change. The structure is a 48 floors 35x35 meters. It has a diagrid on the facade. Supports and columns are completely fixed (i mean with no degrees of freedom). There are mesh loads in each plant (4kN/m2) and also mesh loads acting as wind loads (kN/m2). PD: if you know how to recreate a wind load, it would be great to know ( better than using a constant mesh load). Thank you very much in advance.

Difficult to answer, could you share your model (definition) to take a look?
