I raised this in the Builder Blocks Apostle thread but thought it would go off topic. Why can't military units from multiple civs at peace stack? It seems a limited exception for 1upt could be made for that. It just seems ridiculous that you can't move through allied territory b/c they have too many military units. Even without 1upt, I THINK all prior civs did not allow this to happen (am I wrong). Even under a non-1upt system I don't understand why they wouldn't allow this. If war is declared, then the pieces can all go back to home territory or whatever.
