Download - startupscript.zip - Google Drive
Extract to your “mods” folder.
Add this to your user_settings.json,
"mods" : {
"stonehearth" : {
"world_generation" : {
"method" : "tiny"
}
}
}
Don’t forget to add a comma, depending on where you insert this 
If you choose to download the file, here’s what to do.
Open up
startupscript/server_init.lua
Add this
self:place_citizen_with_job(pop, Point3(camp_x +16, pt.y, camp_z +12),
"stonehearth:jobs:mason",
"stonehearth:mason:talisman",
"stonehearth:mason:workbench",
Point3(camp_x+18, pt.y, camp_z +11))
for i = 0, 6 do
self:place_item(pop, "stonehearth:resources:stone:hunk_of_stone", camp_x +11, camp_z+9)
end
This will spawn in a Hearthling already promoted to a Mason, and have him/her place their workshop for you. 
As a side note always start new games when doing testing for mods, I’ve encountered many many times where saves maintain certain data, even if you change your .json’s, you will not see some changes in-game.
@Azhrak I’d be glad to assist you if you are having trouble, just post a download link or pm me.
