I am not the author of this program. This program is PawelS' modified version of the official AoWSM Editor. I have uploaded it to AoW2 Heaven with the permission of PawelS.
AoWSMEd_x3 is a modified version of the official AoWSM Editor.
It has the ability to add structures to cities that lack the prerequisite structures. For example, it will allow you to add a Teleportation Gate to a city that does not have a Wizards's Tower, Wizard's Tower II or Wizard's Tower III.
Place the file "AoWSMEd_x3.exe" in the top folder of your AoWSM directory (e.g. "C:\Program Files (x86)\Age of Wonders Shadow Magic"). You can then run the program directly, create a shortcut to it, etc.
