Little Lisa's Recycling Center produces blueprints now

I was just searching to see if the blueprints continued to collect after reaching the weekly goal. The building keeps producing prints, but can't see that they are accumulating anywhere. What's really great about this building though is if you're impatient, like me, and are just short a few prints, you can get 450 to finish off a prize for only 2 donuts. Cheaper than speeding up at the menu.
