Hello,

There's a bug with the Administrative Complex, also known as building_bureaucratic_3 in the game files. You added this building back in, which was commented out in vanilla Stellaris.

The bug is that building_bureaucratic_3 isn't considered part of the colony type that building_bureaucratic_1 and building_bureaucratic_2 are. So a planet specializing in bureaucracy - gaining the extra bonuses simply for building a lot of "building_bureaucratic_X" compared to other types of buildings will suddenly lose this bonus when upgrading your building_bureaucratic_2 to building_bureaucratic_3.

This bonus is declared in common\colony_types\00_colony_types, starting from line #2300 in Stellaris 2.7.2. As you can see here, building_bureaucratic_3 isn't part of the weight for this bonus, simply because in vanilla, this building doesn't exist.

I hope this was helpful in making this a very easy fix for you. Any other buildings you might have "unlocked" are also likely to suffer from the same bug.

Thanks a ton for the bug fix mod!
