The Done button is in the middle, while it should be at the bottom
The Skill, armour, and move CP cost are done incorrectly
Yeah, not bugs, but it still sucks.
The real equation for CP is <a href="http://www.brikwars.com/rules/2005/7.htm">here</a>.
Where t=structure level, s=size, m=movement in inches, L=skill level
And don't tell me this is impractical; a minifig could be made of forcefield!
