ziggs animation bug

Hello riot! i just play a game with an enemy ziggs that all other player and me didnt see ziggs ability. all we can see is the red circle of the ult and the explosion, the c4 is ok, but with the q we only see the boncing "flame" but not the bomb and for the mine field we only see the blinking of the mine not the bomb. The fact is that in the replay we can see all the animation. but if you look in the chat everyone say that ziggs animation are invisible. so i do not have anyscreenshot and maybe this will be a one time bug but please check for this.

thank you!
