Im new to minecraft, how  do the updates  work ie how do they affect  worlds that  have already ben created previously ? Spacificly I have  a survival world  that curently is  bugged  (villagers wont breed ) I have  looked up the  bug and they have  an open ticket on it  ... Im wondering if when they do implament a fix will it  fix  my world? Or  will  I have to recreate everything from scrach since Iv allready "discoverd" the  villagers I had planed to use  in my Iron farm. Is it pointless to do anything with this world till they get  it fixed?
