there's the option to give templar chapter house to entire faction, if you look again at the hidden resource list in export_descr_buildings you will see "norway" "sicily" etc etc
you can make chapter house available in any of the faction's original settlements, like if you add england to the list then templars will available to any of the english settlements, however, if say england conquers Paris they wont get any templars there, unless if you add france to the list too
it's the only option that allows you to continue your campaign, the only one i see atleast
EDIT:you can try this, go in export_descr_buildings and find the templar chapter house building,
you should find something like this, the important part is at the end
Code:
building templars_chapter_house{
convert_to templars_chapter_house
levels templars_minor_ch templars_major_ch
{
templars_minor_ch requires factions { england, jerusalem, norway, france, scotland, denmark, hungary, poland, papal_states, milan, sicily, venice, jerusalem, } and hidden_resource templars_chapter_house and not building_present st_johns_chapter_house
change it to this
Code:
building templars_chapter_house{
convert_to templars_chapter_house
levels templars_minor_ch templars_major_ch
{
templars_minor_ch requires factions { england, jerusalem, norway, france, scotland, denmark, hungary, poland, papal_states, milan, sicily, venice, jerusalem, } and hidden_resource templars_chapter_house or hidden_resource papal_states and not building_present st_johns_chapter_house
"or hidden_resource papal_states" has been added, i put there papal_states so now templar order should be available to Rome and Ancona, you can put there any of the hidden resources
