Nevada.updateTransferGas(uint256) (Nevada.sol#365-370) uses literals with too many digits:
- require(bool)(newGas >= 21000 && newGas <= 100000) (Nevada.sol#366)
Nevada.slitherConstructorVariables() (Nevada.sol#27-393) uses literals with too many digits:

balanceOf(address) should be declared external:
- Nevada.balanceOf(address) (Nevada.sol#114)
Use the external attribute for functions never called from the contract.

Nevada.selmaTaxDiscount(address).diamondBalance (Nevada.sol#223) is a local variable never initialized
Nevada.selmaTaxDiscount(address).platinumBalance (Nevada.sol#219) is a local variable never initialized
Nevada.selmaTaxDiscount(address).discountMultiplier (Nevada.sol#217) is a local variable never initialized
Initialize all the variables. If a variable is meant to be initialized to zero, explicitly set it to zero to improve code readability.

Ensure that all the return values of the function calls are used.

Nevada.initPresale(address).newPresale (Nevada.sol#386) lacks a zero-check on :

Check that the address is not zero.

Variable 'Nevada.selmaTaxDiscount(address).platinumBalance (Nevada.sol#219)' in Nevada.selmaTaxDiscount(address) (Nevada.sol#216-228) potentially used before declaration: platinumBalance > 0 (Nevada.sol#220)
Variable 'Nevada.selmaTaxDiscount(address).diamondBalance (Nevada.sol#223)' in Nevada.selmaTaxDiscount(address) (Nevada.sol#216-228) potentially used before declaration: diamondBalance > 0 (Nevada.sol#224)
Move all variable declarations prior to any usage of the variable, and ensure that reaching a variable declaration does not depend on some conditional if it is used unconditionally.
