You can own 2 tiles of the same type, but not from the same hex
You can not collect 2 tiles from the same hex (even if you discarded the first one),
but you can touch both location hexes on a sector to collect 2 tiles,
1 from each hex. ("A player may only have 2 identical location tiles
if they have build a settlement next to both identical location hexes of that game board section.", rules page 3)
Place the 15 nomad tiles on the table picture side up, shuffle them,
then randomly draw and place 1 tile for each nomad space on the game board,
now with the pictogram side up.
