Bosses With Special abilities (BUG)
 

I notice whenever i do a boss that has a mechanic where it gives you a special button to use throughout the encounter Such as ultraxion or the last boss in Shadow pan monastery. The button does not appear which tends to make it impossible to do the encounter. is there a fix for this aside from creating a macro for the spell?

also another problem i've ran into while leveling in MoP was the inabilty to use some items via the little button next to the quest tracker discription. I was forced to place the item on my bar instead. not a big deal, just wanted to let you know in case you already didn't.

edit: found other people are having the same issue after reading more. so i guess its a known issue.

Until we get it fixed, you can create a macro '/click ExtraActionButton1' and place that one your action bar, then use it to get those clicks off.
