Yep, I've repeated this too now:
1. Start by build 3 additional Engineers.
2. Set the 3 engineers to create Logistics Centers.
3. As the Metal resource drops below 0, hit the ESC key (this calls up the Pause menu).
4. Resume the game and order the Engineers to stop building the Logistics Centers. The Logistic Centres should just instantly complete.
5. Order an Engineer to build a Factory. it should also appear instantly.
Well done Krasmoth!
