So first off, I'm using minecraft on my pc version 1.8.9 and no matter which version I use, I'm still getting the same problem.
My problem is that I have this world that I built a farm house type of thing in, I was in creative mode when I built it. I decided I wanted to expand my house and farm so I switched into survival mode, My food bar and hearts bar showed up, So naturally I assumed I was in survival. Well I went to kill a sheep (since i was hungry) and I did not get the meat or wool, just one experience rolled my way. I figured it was nothing and tried again, same thing happened. Then I tried digging out some dirt with my shovel, It broke the block but the block disappeared and I had seen it for a split second before POOF gone. You know how you break blocks in creative mode? well it was exactly like that. It took me the same amount of time to break a block as in survival but disappeared as in creative. I had my bf log on and see if his Player did the same and only when I was near him, would the same thing happen to him. So I moved back away from him (about 10 blocks away ish) and then he was able to break and pick up the blocks normally. I've tried restarting my laptop, switching versions and In other worlds it doesnt happen. Just this particular one.
Can anyone help me please? :(
