i dont think its fixed cuz it just wouldnt work...its like blitzkrieg said not even in L2J that would work...
P.S. a Shadow weapon is a weapon you "rent" and use until times up on your rent.
there was some information a while ago that was leaked, that said that GMs would let partys of botters go unbanned cuz if they were to ban them they would lose a lot of cashhhh.
i think it will most likely only work on servers where you can still climb mountains (bugged geodata), if you can climb mountains you can do this bug, thats my opinion and im sticking to it XD
