Yeah I'm not sure why you didn't get them. Playing the Barataks, right on turn one using console commands I get the miners and the template when researching that tech. Did you happen to delete the base miner template in a previous game ? That may be the cause of this issue.
Loading the save, I see that you don't have the miners template; thankfully you can design one easily in the shipyard: I just did in your game.
Still, I'll forward it to the team.
