We made an update to mods in this release that may cause old mods to break your existing game. If you’re seeing a black screen on load, right click on Stonehearth in steam, go to properties > local files and open your local files folder. Inside the Stonehearth folder, look for mods, and copy old mods out to a safe place on your hard drive till the game loads again.
We’re looking into this now, adding @ayazar
Sorry for the inconvenience!
