I have successfully built three base that function normally but Bases #4 and up I can not update or change the soldiers for the drop ships or the equipment on the interceptors without it crashing. All the other base functions for bases 4 and up work great. I am a winxp user.
Another thing I noticed is that after building 2 workshops and staffing them with 20 workers everything takes 1 hour to build. Works great for funding an army but may need some tweaking in the future.
