My Republic Zabrak's eyes have also changed. They went from yellow to white after the update, and I'm really concerned with how long it's taking for it to get fixed. I haven't done the new flashpoint with her yet because I wanted to record it, but with her new alarming eye color I have to wait.
Here is a picture reference of the differences using the first one I could find where you can see her yellow eyes.

I went to the cartel appearance changer and there isn't even an option anymore for the eyes she had. I really don't like these changes... Even my other characters who were lucky enough to keep their old colors still look like they have cataracts, and the color isn't as vivid as before.
