Ok guys, so here is the issue - I have just recently resigned from the Family membership and now I am a short-life but proud looner. The problem is that I cannot join any other faction.
After resigning from the Family, I have got 3500+ reputation from the Jim & Jack & Joe Lawyer Agency faction (the opposite force to the Family) and its base became visible for me (with simultaneous disappearance of the Family facilities; The Family reputation = 0). When I came to the Lawyers base I could spawn on the courtyard or inside the base (while cannot cross the main gate of the base; moving inside the base is only possible by town/world button).
When I was already inside, I wanted to seal my membership with the new faction and get a safe spot. Nevertheless my nick was completely white (fortunately The Lawyers curiosity didn't come along with the bullets), I could not become the member of the faction. In the dialogue chart with the quatermaster Stark I could only resign from the Lawyers for on and on and nothing had happened.
So here are the bullet points of the problem:
1) After resigning from one faction it was impossible for me to join to the other.
> It would be great if you could choose which faction you would like to join afterwards, depending on your reputation stats (just like it is described in the AoP wiki).
2) Reputation
> Why did the reputation of The Lawyers stats grow so rapidly after resigning the opposed Family? Shouldn't it changed more slightly like the reputation stats for the abandoned Family?
