The code above is used to update an array (the winning input weights) after the best set of weights for a neural net have been found. After the winning weights have been updated, 3 more random weight sets are created with the winning weights as a starting point. I have monitored how many times the if statement has been executed, and done a print(winningResponse) type thing in Unity3d to see what is changing and what is not. The winningResponse only changed when the if statement is called. The winningWeights, however, change regardless, which should not happen.

EDIT:
Could it be that the fact that I'm trying to set an entire array equal to another array is messing with the program?
