For the past few weeks, the Wizard emoticon was replaced by a partly-loaded Garrus icon for me. I thought it was a joke, or new icons were being implemented, but nobody else seemed to notice (and I hang out in the Garrus thread, so...yeah, they would notice). When I tried to use it and ask other people about it, it reverted back to Wizard.
It's fixed itself, so not a problem any more (not really a problem in the first place, I don't use emoticons), but I thought I ought to mention a possible bug. Has anyone else run into a mystery emoticon?

^ This is what I saw when I posted, and whenever someone else used the Wizard icon, it was also Garrus.
