[2019] Invisible Nunu bug still in the game. It's a lol replay, not a recording of the live game, so we can see Nunu here. However,you can see that I have no clue Nunu is on my lane until the snowball exploded, and the pings of my teammate that was surprised Nunu appeared in front of my face in an instant.

If you seriously have an EASY repro for this bug please send it my way. The reason it's hard to fix is that we've found it impossible to repro reliably

One of the reasons Nunu isn't disabled is that we don't think the bug is exploitable. It's extremely rare and (as far as we know) almost impossible to do intentionally. Might not even be a Nunu bug, could be something messed up in the code with channels that let you keep moving (have heard stories of it happening with Vi and Pyke for example). Not as easy as it looks to just fix on Monday ;(
