Actually I had the same issue with this CC and not looting but didn't say anything as I thought it was on my end. Now I see someone else having the same issue I'm not so sure. It's odd because he loots for a while, and then stops looting but will then randomly loot dead corpses as he passes by the. I tried clearing my wow cache, shutting down honor buddy, restarting pc, etc to no avail.
I went back to the stock mage.cs for now (which loot 100% of the time) but will try this cc out again with the new version of HB and see how things go as I really liked it.
I modified the stock mage.cs to re-target polymorphed mobs though (I store a reference to the last polymorphed mob so I can check next combat call if I have no target) so would miss that as it looks less botish that way. Also modified it to use frost nova and wand when next to no mana something neither did very well.
