I then launch minecraft, go into the world, open advancements and my advancement is not there. I even tried to revoke all the advancements and re get them but it still did not show. Why is it not working? Please help.
New problem. So I managed to fix the old one that I was having but now I have a new one. I want to get a reward for completing the advancement, but the advancement will not show. Can someone tell me what I have wrong here? P.S. The_Shadow, when I clicked on that link it said page not found.
