OP Gamebreaking Nasus Bug

I was recently playing a game of League as Nasus, a character I haven't played or seen played in quite some time. I was doing pretty well until I went back to the fountain and bought my homeguard enchantment. This is when I discovered the bug. As I left the base to help my team defend the middle lane, I was shocked when Nasus began bounding towards the lane. As far as I knew, Nasus' homeguard animation was supposed to be him running on all fours like the dog he is, with his stick in his mouth, because that's how dogs hold sticks. I don't know if this has been brought up before, but I don't think I can play this game again until the bug is fixed. League is a game and I really enjoy, and I don't want to stop playing because of something as trivial as this. -Much love, platypusman948
