More issues:

- Rarities of each part is not encoded in the contract (It just depends on how the application logic decides to decode the uint). They could swap Shadow parts with Gold and the contract doesn't do anything to prevent that

Since this is a comment, if 23 is generated, a unit will be generated, which they _promise_ will be a lamborghini. Pinky promise.

There is also nothing stopping them from bumping the drop-rates for the final game. They promise 2%, but since this contract is void post the pre-sale, it will have to be a new one and it could have a 80% lamborghini drop rate!
