[GAMEPLAY] Gnar- can ult while he is mini gnar

On , you can use his ultimate while he is a mini . I asked the enemy team they said it is a bug, but still i am not sure if it is bug or hack. Most properly its a bug.

I don't know how he did it so i can't provide you a steps. It can be only done in Nexus blitz. as the enemy team said.

I have attach a clip of it. https://streamable.com/edit/1twfh
