Hi,
I've discovered an easily reproducible UI bug - unique to the Frost Mage spec. When casting Frostbolt on targets who are immune, or just missing your Frostbolt casts - you generate a stack of Icicles buff. However, the mage does not generate actual Icicles (none to be found above the Mages head
![Roll Eyes (Sarcastic)](//cdn-wow.mmoui.com/images/style_mmoi_wowi2/smilies/rolleyes.gif)
). What's more weird is that you can actually cast Glacial Spike once you generate 5 of those 'dead/fake' Icicles and the fake Icicle buff stacks won't even decrease/get consumed.
