How has nunu not been disabled already? This bug is unacceptable.

Twice so far, once in the last patch, once in the second to last patch, I was in lane, away from any fog of war/bushes etc. In the middle of lane farming. Suddenly I get knocked up and nunu is right next to me. I checked the replay and he literally rollied it right down the middle of lane right in front of me. The first time I was mid and he rolled it from the path on the other side of the wall from the river. Same deal. They said this was fixed? Well it's not.
