I can crew with people and it will let me enter. many times in the last week I was even able to be the leader and get into the mill. now if I try to get in as leader of a crew or even by myself, I get this message, "The door won't open for you. Talk to Gustav, or Crew with someone that has previously entered the Saw Mill." I'm level 10. I did the mill YEARS ago. I should be able to get in!
