The past 3 times I played against Mundo bot I had the same bug. It really makes the game un-winnable.

Can confirm on Naut's Q/Anchor grab does have this issue as well.

This bug seems to be affecting skill shots and some auto attacks for most champions. I noticed that any ranged champions' auto attack projectiles were invisible.

Ashe
Nami

Purple:

Jarvan
Shaco
Draven
Teemo

Latency was
30-34
