I found another bug that when you make a One handed sword and give it to the customer, there's a chance that the board where every sales are registered that the weapon will be displayed as "One handed sword", in this case it will be sold at about 11$ (with fancy handle) and other times, it will display as "Bronze one handed sword" where it will pay a descent amount of money (27$ with fancy handle) Though i bet it's less for beginners as i got like 4 points in charisma.
27$ Is still going in no profit because of the worth of the bronze, guard and fancy handle but of course the other version (11$) is just a plain loss.
