[GAMEPLAY] Nunu's ''W'' Bug

Nunu's ''W'' - Snow ball, didn't disspear from the game since the beggining after he used the 2nd one, the first one went correctly without any problem but the second one just stuck there the whole game, also it wasn't only me who was seeing it.. my whole team said the same, not sure about the enemy team, we didn't ask them :)

Here's the game, items, champs we played and runes we used : https://imgur.com/FWfvgJF and don't forget to watch the video above in HD .
