I hovered over my name to check my HA and for some reason I'm wearing a yellow tank. I went to my wardrobe and it doesn't seem to be in there.

Any ideas?

It seems fine now...but that's been happening a lot lately with lots of people. I thought it wasn't going to affect me about a week ago, but then my Clingbaaaaaa (head item) turned into one of my wigs (i.e. it swapped the two, so i was wearing two wigs at once instead of a wig and something on my head). Needless to say it looked odd, but going to your wardrobe and re-saving your HA seems to fix it.
