I understand - the restriction is mostly on my time and effort. Most of the time players don't need more than one shield in the same day, and it's easier for me to put all the logic together as one "create shield" operation that can only happen once per day and makes the best shield possible instead of having multiple once per day shield-making options. Part of the once-per-day restriction I think was from an early simple version of my daily reset logic, which is now a bit more robust and able to remove multiple shields from Graham's inventory, so maybe I can just remove that restriction. The best (but most work for me, for honestly pretty minimal reward) would be to only let you craft a second shield if you are able to craft a better one than you did previously. I'll think about this and maybe add something in to the blacksmithing / woodworking updates that happen in the future.
