I have visited all the locations the Tinker said the nomads were and I have barely seen any. Maybe 1-6 (6 is really pushing it, I only say 6 cause I saw a couple of corpses combined with the 1-2 I killed) nomads per tower site and I have not seen any randomly roaming the desert whilst flying to other locations.
The mission description says he needs Gift Wrapping Paper, Beautiful Ribbon Bow, Super Effective Tape, Paper Clip, Delicious Chewing Gum, Plastic Container with Strange Powder Electrical Wires. I dont know how people are going to collect these items efficiently with so few nomads.
So please, tell me I am doing something wrong, or tell me more will be popping as the days go by? If neither are true, then more nomads need to be up.
