CTCToken._totalSupply (#1066) is set pre-construction with a non-constant function or state variable:
- 99000000 * (10 ** _decimals)
CTCToken._tTotal (#1070) is set pre-construction with a non-constant function or state variable:
- _totalSupply
Remove any initialization of state variables via non-constant state variables or function calls. If variables must be set upon contract deployment, locate initialization in the constructor instead.
