What happened to them? I played Legends at a friend's (why I bought the game, actually) and we played the "Galactic Republic" scenario, and it was lots of fun to edit. Is there something I'm missing?

<t> Playing the Ancient Galaxy scenario. I've completed every level of research for the virus and built the Bioengineering facility at Sol 1, a desert planet- but from what I can tell, nothing has happened. Is there something I'm missing? Do I need to deploy the virus myself? Thanks in advance.<br ...
