Yeah. I already found them, thanks.
West of Optis workshop, near the Yellow cave, is the bad directions, tbh. I just started the game and don't know where is Yellow cave, and first time I travelled west of Optis Workshop I found only the junkyard.

My bad...There was a bug that prevented the vagrants from appearing next to the yellow cave. Now it should be solved.
