I've pretty much finished the game with all the research complete but I can't build my last booster. I've looked and I can't build it in any of my cities. I have everything else and 2 boosters but not that final one. Please can some1 tell me how to fix this.
Edit: just fixed it, if any1 has this problem u need to build a spaceship factory to build the last booster.
