This patch:
- renames template_structure_civic_civil_centre.xml to template_structure_civic_center.xml
- renames template_structure_civic_civil_centre_military_colony.xml to template_structure_civic_center_colony.xml
- updates all simulation files that use them accordingly (did a grep -r 'civic_civil')
Not only was the old name unnecessary long, but also potentially misleading: e.g. template_structure_civic_civil_centre_military.xml doesn't exist. Just “center” and “center_colony” is clearer, more correct, and more consistent with other template_structure_*.xml names.
See also D2036.
In a future patch the {civ}_civil_centre.xml templates could be corrected to {civ}_civic_center.xml, but that also means updating virtually all map files.
