I am having an issue where, when I add local Rico settings to some buildings, after a reload, buildings disappear from both the regular menu and the Rico settings menu. It doesn’t happen with custom workshop assets, but only with unique buildings that come with the game. So many are missing and I have no idea how to get them back, as they are no longer listed in the Rico settings menu.

EDIT:
When I turn off the Rico mod, the unique buildings are still missing. Upon loading a save game I get the error below. Happens with or without the mod turned on.

Broken assets:
Europe monument: city_hall: private building cannot have manual placement style
Monument: Posh Mall: private building cannot have manual placement style
Modded pack 2: electric car factory: private building cannot have manual placement style

etc etc etc for like 20 different buildings.
