Hi, when i build a lot of cities i faced certain buildings with problematic hitboxes:
Extremly large hitbox: Treasury, all crafting schools like cavalry school, archery school, Embassy, Empire Bazaar.
I recommend to make this hitbox a lot smaller.
Large hitbox: Palace, Crafting Hall, Advisor Hall, Dock and Trade Dock (can't place decorations on land next or behind the Trade Dock).
A bit smaller hitbox will do. Because on this buildings you actually have to build the decorations first and then place it, somehow the game accepts this more then the other way around.
Just a little bit too big: Gear Hall, Arena
Just a bit will do but now it is still not possible to place vase etc. directly next to the building.
Special hitbox: Persian and Roman Baluster.

I made this picture to show: Green is the anchor point were the cursor is, Baluster seems to circle around this point. Red is the distance from cursor to Baluster. Yellow is the area, were you can't place anything else. On the other side of the Baluster it is possible to place things near. It would be great if it would be possible to place things on both sides. So that the hitbox (yellow) is the actual baluster not somethings abstract between the Baluster and anchor point.
