Model duplication and stiffness matrix problems in simple Karamba model

Dear fellow Karamba users,

I’m running in to some problems with duplication of elements when adding multiple pt loads to my model.

Also I have problems when I add a material to my shell – it warns me with stiffness matrix problems.

I can seem to figure out whats wrong

I’ve attached the file – I hope someone can help me solve this.

Kind regards Jacob
