I've talked here before about just how wacky Blizzard's coding is -- they are obviously great programmers (even with all of the 180,000 bugs), but man, when things go wrong in this game, they go wrong in the weirdest, strangest ways. Take the bug above, spotted in patch 3.2.2 by xella over on Livejournal: the female dreanei /train emote is bugged like crazy, but instead of not playing or playing a random sound like you might expect it to do as a software bug, it instead plays a cacophony of the strangest sounds, including a slice of the original sound and then a female blood elf /chicken noise instead. This will surely be fixed soon (and as a few people in the comments over there say, it's probably a bit of file corruption on Blizzard's part), but what a weird bug.
Fortunately, as granular and strange as Blizzard's bugs are, their fixes are just as minute: tree druids will be happy to see that, since patch 3.2, their treeform now actually moves correctly after Levitate is cast on it. It's a small change, sure, but every little bit helps with immersion. Maybe someday we'll see mounts do it, too.
