[GAMEPLAY] Lulu Q Range Indicator missing

Sometimes the range indication for Q is not shown for your pet (see pictures in link). I don't know what exactly triggers the effect but it also reappears at some point. Kinda makes her really hard to play, especially when your pet is on an other unit than yourself, you just have to eyeball the aim.

If i saw it correctly, the indication starts disappearing as soon as I polymorph (W) an enemy. Also it came back a few times when a just polymorphed enemy died. Played two games in a row, occurred for the majority of in-game time.
