Refitting ships as intended?

[IanD (OP)]

I had half-a-dozen destroyers to refit. Retooled the shipyard for the first quartet and set the yard to refit. Then found that the yard did not use the new engines I had pre-built. Anyone else found this?

Did you tell the yard to use pre-built components?

In VB6 you did not have to do that but in C# you have to specify if pre-built components should be used or not.

Thank you, No I did not specify the yard use pre-built components, that function escaped me.
