It would be cool if we could go back and make the old halloween items. I dropped in and thought it would be cool to decorate my little village with Jack O' Lanterns, but even though I have plenty of pumpkins I can't make any :(
Having to give up your old weapon for a new one is kind of a pain if you don't even know if you'll like the new weapon... gave up my rapid fire bow to get an exploding one, couldn't get the old one back once I realized I was killing my own bat ally with the explosions.
Select the pumpkins in your inventory, and then select the carve action to make the Jack O' Lanterns.
