Ok. So I am trying to get evry achievement in the game, but the problem is there are these 2 acheivements that seem impossible to get. The first one is sniper duel which is to kill a skeleton with a bow and arrow from over 50 meters. Now I have done this but for some reason the game won't give me the achievement no matter what way i do it. Now I normally use creative mode to get all my achievements so i don't know if i need to do it in survival or anything like that. If that is the case then please let me know. The second one is return to sender which is to kill a ghast with its own fireball. The problem woth this is that when I am in creative mode, ghasts never attack me even when i attack them. And the other problem with this is when I go into the nether in survival, whenever ghasts attack me, and i try to hit their fireball back it dosn't go back at all. It just explodes in my face. I have also tryed to use a sword instead of my fists but nothing works. Now again it could be a problem that i do it on multiplayer but I'm not sure. If that is the case of that then please let me know in the comments. I don't need help with any other achievement because I allready have them. I just need help on these 2 achievements. Please help me out! That is all.
