Can't Finish Metheus Puzzle :(

So I found someone to do the newest Don't Starve Together puzzle with me...but there's been a small problemo...I don't know what happened but the person I was doing the puzzle with bailed. I have both our solutions for the part of the puzzle you do before your in-game, but I can't open the chest unless they are with me near it...I don't know if there is a way to reset my puzzle progress or if I can still go through with it...or if there is even anyone out there that will do the puzzle with me =(. My friends don't play this and aren't interested in doing this, meanwhile I REALLY want those skins since I missed out on the tragic torch and all the holiday stuff (I got the torch now that they brought it back but you get my point). The sooner I get a reply, the better...I don't know how much longer Klei is gonna have this thing up
