Hmm, I made a full custom party through LAN. On the Nautiloid my party consisted of my 4 characters, Lae'zel and Us. Which is effectively 6 members. When it came time to recruit Shadowheart she said I'm full up.
Yup ... that is how it has behaved in the past aswell ... Would be great tho, if you could kill Us to make room for her.
I still dont understand why cant we change Race for our hirelings. Lets us play Githyanki as racist as they trully are!
