Shen's E - Shadow Dash doesn't work (rarely happens).

Sometimes when you taunt your enemy he ignores you and contiune to run towards your ally. It happened to me like 2 times out of 5-6 games with Shen. OFC i wasn't standing before/behind my ally so it could look like enemy is running towards him. I was running/standing in different direction/spot. I could clearly see that he's taunted and he ignores me and run in different direction. It happens very rarely so it's difficult to repeat.
