First of all: my, oh my! Now, this will be interesting to follow
Can’t wait to find out more about the super secret awesome tunneling project.
Secondly: non-functional mods?!
As far as I know, all versions put on this forums are fully functional - no bugs have been reported so far.
The only thing I can think of that would make your mod not work, are described in the “Mod Compatibility” section:
There should be a dead give-away if your mod is working or not - and you don’t even have to have any Hearthlings die to find out I put a “Poyo Statue” in the Mason’s recipe list, just for this!
But seeing how I’m sometimes a pessimist, I’ll assume it’s not working for you May I ask what version you’re using and what issue you’re facing?
Edit: Ps. in case it’s not working for you, I wouldn’t mind to have a peek at your stonehearth.log with all text from starting Stonehearth up to the point after just booting up a game (new or saved does not matter to me).
