I deleted the airfield/factory maps and added aircraft performance charts using the "delete" and "add new map" functions, leaving only the "normal world" map. However, when the war was won and the map changed, my charts were uninstalled and the airfield maps restored. I'm guessing this will happen with every new map. Can I just save the "maps" folder (with my charts) and restore it after a map change to avoid the delete-and-add process? Can the new .lst file be copy and pasted to my folder of custom maps?
