Im assuming the 'Robot Upgrades' are recipes in the assembly machines, however, neither of the upgrades regarding the logistic and construction robot upgrades show. I have the single technology unlocked which this mod offers. Am i missing something?

did you turn the setting on with the startup

I was playing for a while past the point of getting the Nuclear Robots, then went back into the options to turn the setting on to get the recipe, but I don't see the option under my T3 assembler.

I started a brand new game, worked my way up to nuclear robots and NOW I see the upgrades. But on a reload of the game where the option was not set, the upgrades don't appear.

I found the console command to reset this particular research:

/c game.player.force.technologies['nuclear-robots'].researched=false; game.player.force.set_saved_technology_progress('nuclear-robots',0.99)

(Note this will disable achievements)

I then re-researched Nuclear Robotics and the upgrade worked. So I'm not sure if there's something you can do with forcing the recipe to be available if this Nuclear Robotics has already been researched?
