the option writes to the same locations either a high number or a zero..
if you still have "more" then the game itself is storing most of that item in yet another location and then adding the two values together.
we did this to try and help people who say they have more than "possible" of nukes more than anything.

Thank You!
Not sure if its against the terms to post links here but there's an interesting Kotaku article about a group trying to remove nukes entirely from the game in order to unlock a secret ending.
Links are ok so long as it's not to bad content like another trainer site or porn or warez etc.
