I can’t find 84195 in my copy of the source.
Generally, this comes from two places. Either:
A) you put the same RG seed in two files (perhaps the original and a copy you modified)
you created the RG ( static numeric::random::RandomGenerator RG(84195); // <- Magic number, do not change it!!!
) in a header file, then included the header in more than one place (thus duplicating the RG).
