So, I've defeated the Dacian faction long time ago, I've appointed a tribune which came from a different faction, as the lord of a castle (I think Potaissa), then I've heard that he was betrothed to my daughter and I've arrested and executed him.

Now the castle have no lord but I can't seem to find any way to confer it to me, I can confer it to a companion but that's not what I want. I tried to speak with everyone in the Atrium Augusti but yeah, i cant seem to find that option.

Help please ^^
