The realm rejoices as Paradox Interactive announces the launch of Crusader Kings III, the latest entry in the publisher’s grand strategy role-playing game franchise. Advisors may now jockey for positions of influence and adversaries should save their schemes for another day, because on this day Crusader Kings III can be purchased on Steam, the Paradox Store, and other major online retailers.
Thnx, I changed the "<16" part to "<21" (for the last tech level) and it worked. It would have probably worked with "<20", but I added one more above the max in case "<20" would not be enough for the last building.Have a look in common\scripted_triggers\plus_scripted_triggers.txt, 'can_build_more_buildings' and below. Should be easy enough to edit.
