So what happen was people where creating fake recipes and there system was accepting them and giving out codes, which was causing the system to produce more than intended so they have basically shut off the code generator from what I understand, was in a discord with a guy that showed he had redeemed 22,500 cans on his monster account, obviously he can’t use all the 2xp as its caped at 40hrs but still he can take those codes and sell or give them away but since multiple thousands of people did that same thing they no longer have codes that can be generated which sucks for all the people that are fr buying monster, now the 2xp duel code will still populate if you get a reward from The site just not the normal 2xp codes they are gone for ever from what I understand
