Hello I am having a problem in my world I have just noticed today....
I created my world, on the day of 1.7.2 (July 16th) and have had no problem and have loved it since it had no snow. now since I have only been in half of my world (I only build farms) and have decided to expand when placing blocks ice has started spreading and when I misplace a block and try to destroy it it just re-appears seconds later I have tried multiple things to fix this problem :(
-delete the ice
-reload the world
-save and exit the world (and re-enter :P)
but have had no success, and since a farm will be there it would be quiet difficult to pass other -.- and Its a big section of the land :/
