I'm Human Male Fighter getting called "her" all the time....
So far the only bug I've come across is this one. I thought I was just hearing and reading things wrong... or they were talking about someone else. But, when I woke up after closing the first large rift and the townspeople and street chatter were referring to me as She and Her it hit me... They've mistaken my flowing golden locks and slightly "too" pinkish lips for me being a woman! Oh, the huMANity!
Bioware forums stated they are aware and looking into this problem, but I just rerolled a female in case it doesn't fix retroactively.
