Building Problem

[Omanes Alexandrapolites]

Hi and welcome MindLich,
Yep MindLich, I, sadly, know the problem. I, however, often resolve it by destroying the enemy government buildings completely and that, strangely enough, opens up the regional pacification building for me to implement. It's an odd way of doing it, yet, perhaps, it could aid you to solve the problem. Good luck, cheers!
