I'm not sure if anyone else has this problem, but as soon as I updated last night, logged in and grouped up for a Heroic my chat would randomly say "**** says: aa"; it wouldn't just do it once, but sometimes 4 or 5 times in a row, then nothing for a minute and then it would do it again. I haven't changed any keybindings or macro'd anything new.. but as soon as I wasn't in a group, this didn't happen anymore. This same problem was happening to a friend as well. I really have no idea how this happened, any ideas or hints? Thanks!
