With a little text editing that should only take a few seconds, you can do it. In the export_descr_guilds.txt, look for:
Code:
;------------------------------------------
Guild templars_chapter_house
building guild_templars_chapter_house
exclude st_johns_chapter_house
levels 100 250 500
;------------------------------------------
Guild st_johns_chapter_house
building guild_st_johns_chapter_house
exclude templars_chapter_house
levels 100 250 500
;------------------------------------------
You see where it says "exclude st_johns_chapter_house" and "exclude templars_chapter_house"? Remove those two lines and you'll be able to get both guilds but in different cities/castles. You may not get them at the same time within a few turns but you will get them. As soon as you earn enough points for both guilds.
