I have a question about automatic terraforming when a civilization that has automatic terraforming adopts a religion that also has automatic terraforming.
Specifically, in my current game I'm playing as the Illians and adopted White Hand. The Illians form Frost Climate, according to the 'pedia, while White Hand forms Glacial Climate. So I'm having tiles switch back and forth between Glacier and either Taiga or Tundra. The problem is that when the terrain changes I'll temporarily lose a resource (eg, Mushrooms, Cow) until the terrain changes back and the resource comes back.
It's more an inconvenience than anything else, but I'm wondering if this is how it's supposed to work. What happens, for example, if the Cualli or Mazatl, or the Malakim, for that matter, adopt White Hand or Fellowship of Leaves, however unlikely that might be? Or if the Illians adopt FoL? (I think those are all the civs and religions with automatic terraforming.) Does the terrain fluctuate back and forth? And is that how it's supposed to be?
