I don't know what you mean by switch lanes. I could store the villagers and release them. But that was all I could do. The game seemed to be waiting for me to do something I wasn't doing.

Gotcha! In the game, you are meant to have the villagers "switch lanes" by sending them home, storing them in the house, and releasing them at a different house. I believe you got stuck because you were not able to switch a villager onto a new lane in order to have them harvest gold. This will be something I address in the game design, thank you for your feedback!
