[Sinapus]

Did you modify the design.txt files for the computer races when you made that vehicle.txt file? I ran a test game with the design manager on and it won't design any attack ship smaller than a destroyer, defense ship or transport designs. It seems to take 'minimum speed' as number of engines, and since the hulls below destroyer on that vehiclesize file you provided have less than 4 engines it won't design them.

Similar thing for fighters. The two-engine fighter hulls in it won't get designed by the AI because it's minimum speed is 6 or so.

Worse, unless I did something wrong those minimums are hard-coded. I changed the minimum speed for the attack ships on the race I was using down to 2 and started a new game and let the design minister work a few turns. Still no attack ship designs using that hull.

Ah well. Back to the drawing board, I guess.
