Proportions - Sphere worlds impossible?

[Mylon]

When playing Proportions, I finally managed to build a sphere world placement generator (the research for it took forever) and just to test things, I tried activating it. During the next turn, I got the message that there was not enough supply to power the component. Granted, there was not enough plating and cabling in the sector (Proportions makes sphereworlds require an astounding 500 cable units and 1000 plating units), but the component also requires 300,000 supply. Well, bases have an unlimited supply, right?

I think there might be a maximum amount of supply for each individual ship (including bases) and this 300,000 number exceeds that.

As a sidenote, in the text for the ringworld and sphereworld components the first says 100,000kt required and the second says 1 MT (and 2 MT for plating) required. This should be expressed as Gt (gigatons), as 1,000 kt = 1 Mt, so 1,000,000kt = 1Gt.

If sphere worlds are impossible given these settings, is it possible to alter the files somehow so I can build sphere worlds without restarting the game?
