No, I did not contact him myself. However, he was questioned about this, ICly, by another character whether he was 'jaundiced and plagued by cataracts' and Kas insisted he was 'fine' and "had a different set of eyes". I read this together.
I myself wasn't offended personally. But I do think that its not the type of words & concepts that should be being expressed in a friendly, international game. Nor do I think its a necessary element of SMA. Finally, what purpose does it serve?
Finally, I grew up in an area that historically held racist sentiments towards immigrant asians with lazy slanty-eyeds being a common asian stereotype so I don't take it as just 'this attribute + this face' when I see those together. To me this would be the same as making some comment about 'charcoal-colored men particularly loving watermelon' or blood moon?
