Retrofit Q

[AMF]

OK, can someone educate this poor slob about how retrofitting *really* works?

I have been trying for two turns now to retrofit some ships I have in the Quadrants of COnflict game, and I've had similar problems with other games. basically it doesn't do the retrofit, sometimes with a "lacking resources" explanation sometimes without. In all cases, I have double checked and I have had what I thought were plenty of resources.

I am assuming that the way retrofit works is that the new (target ship's) components get destroyed and then repaired, and that the cost in resources is the cost of the components that are repaired. In the cases where I have been screaming at the damn game I have had 3 ships that I am retorfitting, the new ship class to which I am retrofitting them has had only a SINGLE component different between it and the prior class, AND I have had more than enough surplus resources to repair said components. It's been extremely aggravating for me and now I'm behind the power curve. Help! Can someone educate me?

thanks,

Alarik
