I have the fire, cleared the debris from the stream, placed the V-shaped rock. I have put 4 hot rocks under the pot of water. I still can't get the banana tree frons on the pot, but that may be that I'm too slow. Once I do get the frons on the pot will the villager carry the hard fruit to the pot?

They do shake the tree and fruit falls, they pick the fruit up but then nothing happens.
