I would suggest keeping track of the progress with variables for the first to items and getting the blueprint with a switch.
If you use variable 4 to keep track of the amount of Galimura+ Automatons killed, variable 6 for Automaton Generators and turn switch 27 ON when you have gotten the blue print, then the quest criteria for the next quest part should be: (NOT the one where you list the tasks)
[rgss]qc = Quest_Criteria.new(["Variable", 4, ">=", 50],
["Variable", 6, ">=", 5],
["Switch", 27, true])
[/rgss]
That way when you have done all the tasks you will automatically see the next quest part.
Note: This will have no effect in-game other than change which quest part is displayed.
