Sexual Reproduction Works?

After consulting my professor on the issues that were present within my
code, we ended up fiddling around with the probability for adding
excess/disjoint genes to the child genome. We set "const double
DefaultDisjointExcessGenesRecombineProbability" equal to 0.0 (can be
found in SharpNeatLib\Genomes\Neat\NeatGenomeParameters.cs"), ran the
experiment with crossover enabled, ran it a couple more times, and
encountered no errors. To see if that is where the problem lay, I set
the probability back to its original value of 0.1 and ran my experiment
some more... I could not reproduce the error no matter how many times I
ran the experiment. I guess everything is okay? Stuff seems fishy to
me...
