Droid Engineer Archive

err, am i doing something wrong? i spent 20k metal and about 5k chemical getting just to first tier of blueprints, i thought i had a ton of resources from my harvestors, i guess not, and thats in practice mode, whats a guy supposed to do to be able to advance as a droid engineer, for now running missions to pay off my harvestors works, but these r small, and it took me about 2 weeks to save up just that much copper, i have other resources of course, but hey no way am i using polysteel to build mice droids anyone have any tips/hints?
