Update bug: Weapon cost glitch on M.D.P.

[aspyhackr]

When i Bought my Mobile Defense Platform, i used all my market turns, and i had to sell all of my offensive weapons to get the 100 B necessary. It wasn't orbiting a planet, and i had like 6B left over, so i decided to get some weapons on the platform.The weapons price said 0, so i went for my usual answer when buying weapons of around 3000. Of course i didn't have nearly enough Naq for this, so i tried 100 and it worked. then i saw the price being 30,000 so i went for another 100, but it said i would need 3,000,000 Which is way off.
i continued adding in increments of 10 and got to 210 before i finally ran out of Naq.

I just wanted to point out this bug with the buy weapons feature on the M.D.P.
