Once a road has been built between 2 cities, what is the purpose of caravans going back and forth? When I replaced a destroyed caravan I didn't notice any difference in either city.
Now I'm not sure if the below incident was caused by a bug or not but I guess I should report it.
I have a caravan and pioneer being escorted by a recruited Ogre. Yes yes very Shrek...
They get attacked by a single low-level spider (I have the auto battle slider down to 0) so the battle options window pops up. But the only active button is the auto-battle button. I shrug and figure the Ogre will wipe out the spider no problem. Imagine my surprise when the spider wins. I'm not sure if by some miracle the spider defeated the Ogre or if there is a bug where caravan escorts are not factored into battles..
