Random Problems

My 3D correlation function matches Alexia's (to within 10^-9 -- which I assumed was rounding differences). However, when I print out the random numbers used to calculate the correlation function they stop matching halfway through the calculation (I am using the same seeds in both runs):

What is even more mysterious is that the number of random values generated is different by 10. This makes no sense because the input files for both functions are the same and both have the same number of mock data points. Do I spend time tracking down this issue, or let is go as it doesn't really effect the end result?
