There is an easier and cleaner solution - moving the declaration of empty
variable inside "for" loop, just before calling SignSignature().

Looking through your code, couldnt see any need for the passing of the parameter,
However, for the sake of cleanness, have moved SignatureData empty inside of loop and removed placeholder functions
Thank you very much for indentifying the issue. |

Removed SignatureData from SignSignature function
By passing SignatureData at the createcoinstake, I believe the values were getting recycled causing subsequent inputs to be signed with the same data (hence the repetition of the scriptsig value in the 2nd and subsequent inputs
For viability, I have not adjusted any other code,
but doing a quick browse, should be able to switch all other function calls to eliminate the need to include SignatureData in SignSignature function.
