No biggie, right?
See, the Kill Command Bug is a mean, horrible monster. The Kill Command Bug says "NO AUTO SHOT FOR YOU!" and then points and laughs as you cry.
Yes, so long as that Kill Command button looks like that, you cannot Auto Shot no matter how hard you try. You can Arcane. You can Steady. You can Multi. But you don't fire any Auto Shots. And that, my friends, is Not Good when you're mid-boss-fight in a Heroic.
Fortunately, amidst my panicking on Ventrilo, my boyfriend picked up Totem Duty for me as I sat there spamming Steady Shot over and over, feeling a bit like a lost and confused kitten. Auto Shot is the solid, unshakable rod that you weave your other shots around, and when it suddenly disappears, the defining aspect of playing a hunter-- the shot rotation-- just crumbles. It was a horrible feeling.
But then, suddenly! The button got unstuck and everything worked again! Hooray!
I wrote it off as a glitch caused by lag or something and didn't worry about it. I got some new epic pants and spent basically the last of my gold gemming and armor-kit-ing them and went to bed satisfied.
This morning I went to go farm motes to make up for all the gold I'd spent on my new pants the day before. I figured I'd level a lowbie pet while I was at it; it makes things more interesting.
And then it happened again. The Kill Command button locked up and Auto Shot disappeared. Helplessly I watched my poor level 67 wolf's health plummet as the level 71 Air Elemental pounded on him; some 40% of my DPS was gone and I couldn't kill the mob fast enough. Barely he survived that thing. *shudders thinking about it*
This is when I alt+tab'd and turned to Google for help. It turns out the Kill Command Bug isn't just something that happens to me, it happens to other hunters too. It occasionally happens with other things, like Rapid Fire. And so long as the bug is active, you also cannot feed your pet or log out.
And apparently, currently the only way to fix it is to crit.
So I ran around using Arcane Shot and Multi-Shot and Steady Shot until finally one of them crit. Ding! Auto Shot comes back home to me and everything is fine again.
It didn't happen again for the rest of that playing session but lemme tell ya, I don't think I'll ever be able to look at the Kill Command button the same way again, at least not for a long time. It sits there taunting me. Just waiting to pounce. Just waiting to catch me unawares and pull the Shot Rotation Doormat out from under my feet again.
So what do we know about the Kill Command Bug? We know that Blizzard is aware of the problem although it doesn't look like it will be fixed until the next patch (it's in the "issues list" for patch 2.4).
We know that so long as the bug is active you cannot fire Auto Shot, or feed your pet or log out.
We know that the bug is "fixed" if you crit or if you forcibly restart the game (/reloadui does not work. It was one of the first things I tried too.)
It has been suggested that the bug is caused by hitting Kill Command too quickly after your Steady Shot. Guess that's what I get for making Kill Command a hotkey and honing my reflexes so I pound it basically as soon as I can. =P I suppose I can take the bug as a compliment then?
Until the patch hits, hunters, be on the lookout. The Kill Command Bug could be coming for YOU next, when you least expect it.
*huddles in the corner and whimpers*
