No! My king can´t... you know get it up

[Belthazor]

I hate adopted usurpers and i always want to keep my line of royal blooded kings, playing as France and basically ruling the world my line is dying out, my king is impotent and he just cant "make" an heir. What should i press in the console to remove his impotent trait? it doesnt work with remove_trait...

give_trait this Fertile 3

If you have more family members, you don't need to worry about your line dying out.

I think he wants the royal bloodline to stay alive, not just the family. (Adopted members.)

Just adding the Fertile trait isn't enough, you need to remove the infertile trait as well so you would type:
give_trait "Name of_Person" Infertile -1
and then
give_trait "Name of_Person" Fertile 3

[Kahn]

give_trait "Name of_Person" +3

[snuggans]

give_trait "Name of_Person" +3

No need to put the name if you have them outside a city and selected at the time. Just putting 'this' in place of the name (but without the ') will do it then.

Since names can be annoying and wont work if they have titles etc.

my family members are 90% comnenus, I tend to intermarriage within the bloodline or give them to other factions, mainly France because J'aime la France.
