I Think you should move that line up before appending the genome to the List

[MartinKlefas]

I made the same mistake as you have here: Genomes are mutable, so any changes to the genomes effect the "version" in the list as well as the one in the wild. it's all the same genome - it's similar to "pass by reference" vs "pass by value" in other programming languages.
