Why players get stuck here
The tower reward and the door it opens are not in the same spot. Follow cutter arrows instead of returning to the tower roof.
Tower and lock are separate landmarks
Yellow Tower accepts five normal red challenge rewards and releases a raw key. The key then follows its own cutter route toward the tunnel mechanism southeast of the tower. Do not return every time to the receiver; follow the directional markers from one cutter to the next.
Take a lantern before entering the underground network and agree on which entrance will be the group's regroup point.
Verify it before moving on
Use a fixed landmark and one set of coordinates when giving directions. If the group splits, leave one player at the landmark while the others search so everyone has a reliable point to return to.
