Those two are the most non essential of all the building work, I just prefer to have the leaves cleared and I use it to train my early villagers so they can build huts better

I'm not really a collecitbles person, I get them to boost points, but after a certain point it's only for prestige really so I'm not so bothered about the tablet pieces.

I suppose people should use their best judgement and choose which building thing they want to have completed, and use the other one for training!
