I'm not in Adventure Mode, but I must use the right tools to destroy blocks. It does it at some points while I am playing, and then it stays like that and don't know why. Does anyone know what i am on about?
2How to write a proper question: 1: Add some punctuation so people can understand the text. 2: Make sure you write the question in such way that people can provide an answer. 3: Add details to the question that you think are important.– user1337Aug 6, 2013 at 21:14
2Some helpful details you should provide: What blocks? What tools? Do you have any mods installed?– UnderscoreZeroAug 6, 2013 at 21:15
Try check this thread out: Blocks won't break unless with right tools?
Are you sure you are not in adventure mode? If it happens in single-player, then try to make another world and see if it's just that one save. If it's on a multiplayer server, then try another to test, if it's the same.
