Do stone walls really surround the "entire" city?
So I'm playing as a plains human and I purchased both stone wall upgrades (the one for 35 crowns and the second for 85). From the description, the 85 crown one said that the stone wall would surround the entire city, but it only replaced the approximate place where my palisade wall used to be. There are some stone towers/outposts on the outskirts of the city but there are no walls between them (what would be an outer wall). Is this a bug?
If not, I suggest changing the description for the stone walls upgrade because it's misleading--it doesn't surround the whole city, just the inner part of it. To reiterate--I have enough stone, I purchased the upgrades, relogged a few times etc., tried clicking and recklicking all the repair walls/continue wall construction buttons but the outer wall isn't building.
