I have problems, the game won't load past 50% at the start. I got the forge event, went outside to get stones and wood to repair it, can't go back to the forge so I quit the game and reopen it
Oh, that's a problem. The sawmill is the end of the current content wall, but I'll look into fixing that bug for the next update. For the time being, you can try editing or deleting the save file, which is located under %AppData%\LocalLow\The Prismatic Forge\Isekaidle\saves
