Cant get Achievements in my world

Well, when I logged in after the village and pillage update the game got rid of All of my maps except one. And when I went on it I had 0 minutes left to play and I couldn't do anything in the world. I don't know what the timer was for I purchased this game about 2 years ago. I decided to redownload minecrat, this fixed the issue then I just recenly relise I can't get achievements on that map anymore. Oh and now the world won't ever save thanks, just add to the fire.
