So long story short I had a problem starting the world on survival. There was not a single mob spawning. So i restarted the world in creative and all mobs spawned flawlessly and therefore i set everyone to survival. But after a long time of playing I realized that achievements are off because I started it on creative. Is there a workaround to get the achievements going again? I saw a youtube video where you can turn it back on but it was on a singleplayer world:(
Thanks in advance.
