It’s really odd that it worked once, and then stopped. I’m wondering if this is related to this bug: [Con] SGT2/A1 Bug: Application doing nothing . (The short of is that you might need to change the permissions under which you run Stonehearth, until we roll out our next build which fixes the bug on our end).
Can you send me private message-me your stonehearth.log and gfx.log files (located in the directory where you installed stonehearth)?
