- One player mentioned that the infectivity is a bit high and that the game is a bit too easy as a result. So I lowered the infectivity.
- This same player also mentioned that the gene selection option can really break a scenario and suggested that I disable the gene selection in order to make the scenario a bit more challenging. I did just that, but I might change it back if too many people don't like it.
- To make the scenario more challenging I also upped the severity of some symptoms.
- I changed the costs for some traits.
- I slightly increased the cure efficiency.
- The four starting traits can no longer be devolved.

Balanced infectivity (abilities).

Balanced infectivity (symptoms).

Balanced infectivity (transmission).

Added a few symptoms and an ability that focus more specifically on infertility. I also added a Custom Victory condition. Now you can win in two ways! ^^
