Optimization - Maintain connection between Design and Non-Design Elements

Hey

 

I am just having issues in optimization, where its runs the file but it somehow doesn't connect all the design and non-design elements. This is how my model is set-up:

 

1.) I have set an objective of minimize volume. 

 

2.) Using displacement and 

 

3.) All non-design elements are set as a 3mm offset from the bolt holes.

 

4.) All bolts have been modeled as rigid elements. 

 

As seen in the image it doesnt seem to always connect all the bolt holes with some design material. Does anyone have any idea how i cant set it up so that it always connects all the bolt holes irrespective of any load going through it.
