I know this is completely unimportant and should go at the bottom of the todo list, but the Chicken Voodoo dolls are not working at all for me. My CW successfully used one on a Batiri during the second week (I think). I didn't try them again until a couple weeks later, but neither my CW or DC has been able to get it to work on anything since, (My GF hasn't gotten any yet.) The race-specific Voodoo Dolls still seem to work ok, but I've tried the Chicken ones on every enemy minion type with both characters and nothing.
Like I said this is an irrelevant, cute gag feature anyway, and everything else should get fixed first (lol), but my OCD wants that dern "Clucky Charms" achievement!
