Thanks for playing, and sorry about this bug. In 0.31 the blacksmith is bugged, but you can sneak past the bug if you exercised at home that morning. 0.32 will have that bugfix, other bugfixes, and some new content, probably this weekend
Download it from here, it's essentially a new game but you can manually move your savefile (it's a file called something like "Save01.rvdata2" in your game folder). Just copy that over to the new install location, pitch the old game, and you're good to go.
New build should go up later today, i'm just still trying to fix an uncooperative bug.
