Is it permissible to have more than one of a particular factory (zone target) per zone, or is the Aces High Strat system limited to a single object of each target type per zone? In other words, Am I going to break something if I stick two ammo factories in a zone?
I apologize if this is specified somewhere - especially if it's somewhere obvious. What I could find by searching seemed to allude to the possibility, but not definitively so.
(and sorry for so many questions!)
