This has been an issue ever since forges were added into the game. For a while though most ppl had the decency to lower their light lvl so they wouldn't mess up other people's attempts. After the guardian games I vowed never to do another forge for the rest of my life. That event ruined forges for me. Forges in general just need lots of work, they are still in a beta test mode like so many other things in this game.
