I can't find anywhere my builders can build after the first place because my builders aren't getting more skilled
where can you build or for your builders to work @ least no big spoilers

Your builders will find the place(s) on their own as soon as they think more huts are necessary (i.e. the population gets to a certain level.)

1-I've noticed a booming sound as I move around the village. Is it the volcano? Is the cave really a mine? Or is somebody blowing something up on the other side of the island?

2-Why are some of my doctors carrying big rocks in the laundry hut?

3-Why (every once in a while) someone sees something unusual by the treasure?

1. if you look all the way to the right side of the island, like straight across from the food bin you will see they are lifting rocks as part of their exercise
2. I'm not sure I've never noticed that
3. That is an error, it has been discussed here a lot, but I believe the newest version (v.101) corrected that... but I could be wrong

I have noticed that. But there is no one there when I hear the sound, and it's louder than the sound of them dropping the rocks. The rocks the doctor's are carrying they seem to be getting somewhere around the cachtus. They carry them around a while, even swimming, then they take them to the laundry room and leave them.

doctors carrying rocks everywhere - not just to the laundry, used to happen with my v 1.00, but haven't noticed it happening since the upgrade.

I get it now and then with v1.01. Sometimes its someone excersing but sometimes I can find no reason for it.
