A bit strange view of buckling analysis with Karamba 3D

I am running a small and simple model for buckling analysis in Grasshopper with Karamba 3D Pro plugin. The model is one section of a telecom latticed tower and it seems to be ok and has a realistic result.

The first buckling-modes governs the situation and the main leg is buckling as expected.

However, in the view in Rhino the secondary members (secondary horizontals and secondary diagonals, they so called) seems to be disconnected.

Is this a normal behaviour or a bug?

Pls see attached a screenshot. Thanks

In the meantime I answered to my question. Basically this was a rigid body in the structural system, thats why I had the strange view. The model was run because it was in equilibrium, but some secondary diagonals "twisted" from the main body due to lack of connection nodes into it.

I found a very useful container in Grasshopper which must be a good friend of Karamba, that is the Shatter

Since Karamba does not really appreciate the lines with points on it, it just did not recognise as internal nodes (which is quite logic if we consider a FEA model) So, for me it worked fine if I have Shattered the line into segments and then convert them into Karamba beams. This made the magic for me in a latticed structure.
