In snow or within 1 tile of snow.

I'm loving your mod, but can't get the Ice Works or Walls to work. Do cities have to be built in snow to work?

Thanks! The problem should have been fixed in the most recent update.

I've had the same problem, using only your mods - northern tribe, southern tribe, earth nation, fire nation, air nomads, and playing your truestart Avatar world map. I also ran into a problem that at roughly the turn swap from BC to AD, I was unable to purchase or change production in the city screen. Also, the extra "pantheon" actually gives at least the follower and enhancer belief options as well. This is a really great mod despite those though, they were fun to play!

Tell me what mods you are using.

Hey, It tried your mod out. When playing the Northern Water Tribe, the tech tree wouldn't move. Not saying I couldnt upgrade. I just couldn't move the screen.
