Vulnerability details

The following structs could change the order of their stored elements to decrease memory uses.
and number of occupied slots. Therefore will save gas at every store and load from memory.

    In Auction.sol, AuctionData{

is optimized to: 16 slots from: 17 slots.
The new order of types (you choose the actual variables):

1. uint256
2. uint256
3. uint256
4. uint256
5. uint256
6. uint256
7. uint256
8. uint256
9. uint256
10. uint256
11. uint256
12. uint256
13. uint256
14. uint256
15. mapping
16. bool
17. bool
