So, i have chosen earliest starting date, with King Vyseris I ruling over Seven Kingdoms. I'v picked Wildling Clan, and when i saw the ability to join SK and gain +12 tax income i was thrilled. All i needed was 103 reputation with House Targeryan, so i improved relation until 80(-20 for heretic religion) and then managed to gather 350 ducats and to send them as gift, thus raising my reputation with them to 104.

In that moment, i should have been able to join Seven Kingdoms and proceed to become King Beyond the wall. But, the button was grayed out as if i didn't fulfill some requirement. Nothing on tool-tip stated anything, so i stopped the game and left the mod. Any hints on what's going on?
