Main campaign building slots

[531800871346315]

I'm interested to know if it's possible to increase the slots for buildings in the standard campaign, or at least if there's a way to add extra buildings once the slots are full. I'm guessing at least one extra slot should be possible, since it's used in the FoTScampaign, but so far i only managed to add an extra locked slot and can't figure out how to make it usable.

Not possible as far as i know. Best i can give you is to add a region specialty to every single region or transform roads to a free slot (yet its levels would affect movement points)

Unfortunately, adding more building slots is not possible.

How does adding slots to the small provinces to that only have 4 slots in their castle town differ from adding one or more to the castles that have 6 slots to start with in order to have 6+ slots per castle town? Is it hard coded?

I think Weierstrass can answer that. He made it for his own mod.
