After deciphering the map I split my forces, half to inform the other cities of the plot, and half to move SW to face the evil. I go to tell the other towns and pick up the reinforcements. The first town gives me a boat, tells me to go to Port Hope. Tarth gives me more troops and tells me to go to Gildan.

This is the problem: My town near Gildan has grown so much that the Gildan capital has no land, they are surrounded by my terrain. When I get close enough to the city, I get the dialogue telling me that while Gildan doesn't have any soldiers, they do have supplies - but the supplies don't spawn, so I can't queue the next part of the quest.

I cheated by building a city next to the obsidian wall so I can teleport over it, but I am wondering if I am screwing up the campaign by doing so. Anyone know a fix for this? You know... other than restarting the campaign and keeping that one city tiny.
