@TheREALHayster do you know if there is any additional dependencies on spouses other than heroes.xml?
My spouses get added as heroes but don't seem to show as spouses in game, at least not when adding them as new characters.
If I overwrite existing ones it works ok. For example if I do this:
<Hero id="lord_english_1a" spouse="hero.lord_english_1b" faction="Faction.clan_english_1" />
<Hero id="lord_english_1b" spouse="hero.lord_english_1a" faction="Faction.clan_english_1" />
I get two heroes added to the same clan, but they wont be spouses.
