If you install this mod AFTER researching robots, you will not have the recipe for servicing broken robots. To get it, you have to use the following commands (which will disable achievements for that save) to remove the research then re-unlock the research.
/c game.player.force.technologies['logistic-robotics'].researched=false; game.player.force.set_saved_technology_progress('logistic-robotics', 0)
/c game.player.force.technologies['construction-robotics'].researched=false; game.player.force.set_saved_technology_progress('construction-robotics', 0)
/c game.player.force.technologies['logistic-robotics'].researched=true
/c game.player.force.technologies['construction-robotics'].researched=true
Mylon, you should either update the mod to check if the recipe is already researched and automatically give you the recipe if so, or update the description to explain this mod should be installed on new saves only.
