Hi Brad,

You get stones from the stone cutter. But in order to get it, you have to get a quest called 'One Brick' which will trigger you to find it in the jungle. So, please go ahead and continue playing the quest queue until you get this quest.

Zieu do you know if there is a list of all the quest somewhere? I think they should unlock buildings according where you are in the quest line instead of level. I'm also suddenly on need of the this item and will have 3 incomplete buildings as a result.
