I have one adept builder; I have one hut, the beach is cleared, the lagoon is unblocked and my builder is starting on a second hut. I'm trying to train another builder by getting them to work on the hut, but they all wander off to try to push the boulder; My builder is getting on in years, and I need another one. Any suggestions? I'm at harvesting 3 science 2 building 2 spirituality 2 fertility 1 medicine 1. Tx...........
