Barbarians and "Change Terrain" Events

[Kull]

This one has been driving me crazy for over a week now! In my new scenario, every time there was a "Change Terrain" event all the Barbarian Units disapeared! I could NOT figure this out. I had never seen it reported and it certainly hadn't happened during "End of the Bronze Age". I tried one parameter after another, and finally discovered the controlling factor:

Kull's Law = "ChangeTerrain" events will cause all Barbarians on the map to disappear UNLESS there is a Barbarian City somewhere on the map.

Not the most earth shattering news, but it may save someone else a lot of grief. It could also conceivably be used to instantly terminate a massive Barbarian onslaught. (kind of like "DestroyACivilization)

VERY INTERESTING!
In Red Front I have had a heck of a time keeping the Barbarians (Yugoslavian Partisans) alive through 1943... until they capture a city in Yugoslavia... Well guess what? On those same turns the allies were bombing Germany = terrain changes!!
Very good discovery... Get two advances free.
