Hunter auto attacks not working!

[MOKO25]

Hey, I rolled a hunter today and immediately saw my auto shot is not working properly. I hit a mob and it doesn't aggro and immediately heals to full hp. When I hit it in melee I can aggro it with no issues. Also using a spell like Arcane Shot aggros it without issues and then my basic auto shot attacks work. Anyone know whats the issue here?

Were you hitting a neutral (yellow) mob? They have a weird reset bug.
