[Gameplay] Invisible Nidalee Spears, Basic Attacks, and Pink Wards

I just finished a ranked game in which I played against a Nidalee whose spears were all invisible except for the orange animation that precedes the ability. Her basic attacks were also invisible for both myself and a fellow player, Blurred Rhymes. Then there was the case of the disappearing pink ward, which sat in a jungle bush on the dragon side of the map in river and would appear to our team and then inexplicably disappear seconds later before we could destroy it. These bugs made the game feel wonky. I cannot give a step by step instruction how how to reproduce this effect, it just happens for some odd reason.
