Turning a Fort into a Settlement: What Stats to Use?

[Odraude]

So my players are looking to turn a fort into their new settlement. It's considered a Fort improvement (Stability +2, Defense +4) and under the Ultimate Campaign rules, it counts as one Barracks (Defense +2) and one Stables (+1 Economy). So which stats would I use? The fort's or the two separate buildings? Or both?

The way I read it once it becomes a settlement it ceases using the "Terrain Improvement" stats for the Fort. You have two separate entries for the new settlement, Barracks and Stables.

Mechanically it ceases being a "Fort", thematically nothing changes.

Pretty much what I figured. Just odd that the stats don't completely match up, but I can chalk it up to the city building outside of the fort walls because of the walls being too small to hold a district. Thanks.
