I don't know if any of the other classes have this problem, but whenever I get shot as an engineer my character (despite being male) makes an unreasonably high pitched yelp that sounds like it'd fit an 8-year-old female character and nothing else. Everything seems normal when I use the voice commands, it's only the shot reaction that does this. Has anybody else noticed this, or is it just some kind of bug?
I think the medic does it too, but I'm not sure. I almost always play engineer so my knowledge of the other classes is minimal at best.
