Argh!!!
I got bit by the stupidity of the AI with that colony module mod. It's putting colony modules in WARSHIPS because they have more supply storage than the standard supply storage component. ()&*$*&*$@*&!$_**_!$!!
So, I had to drop it to standard supply module capacity so the stupid AI won't use a 400kt component in place of a 10kt component with the same supply capacity.
You'd think there would be some simple comparisons done when putting a ship together.
