Sometimes you have a 9999-ton design, but adding the additional fighter fuel tank (1 ton, 0.02HS) makes it 10001 ton. I believe this has annoyed some people a few times as C# has changed ship tonnage rounding from 50-tons to 1-ton.
An even smaller filler is needed in such cases. A 0.5-ton filler should do the job as long as your ship is not 50%+ armor. It can be a fuel tank or a dummy component, or anything else.
I have a solution.
Design the smallest possible power plant of the starting tech.
The size of this thing is 0.5 tons.
The cost is 0.
The research cost is 0.
Name it "Dunnage" or "Filler" or "Ballast" or "Spacetakeupium" whatever.
Thank you, that has worked wonders for me as you can see.
