Nidalee Spears Bug

I was playing a game of 3's against a rengar and a pantheon (only important champs in the game). Rengar bolas would hit me as my spears were flying towards rengar (on target i may add). I would get rooted and my spears would go right through rengar dealing no damage. This happened twice against rengar. In this same game pantheon killed me (cat remember how) but right before i died i cast a spear.. It also did no damage. This happened to me using the Warring Kingdoms Nidalee skin. Please look into this issue. Thanks
