Ok, just checking. @gryffonx’s error looks like it has to do with not finding a file where it thinks the rig should be. Anyway, I’ll let you guys debug this one. 
Ah, right, Steam and Humble Bundle put the files in different places. For Steam, my path looks something like:
Steam\SteamApps\common\Stonehearth\mods\stonehearth\stonehearth_server.luac
The luac is decompiled lua. Various people here have had luck recompiling it, and editing it to get it to work like a normal text file. Check out this thread here: Stonehearth Modding FAQ
