Sploosh joined the team for 0.14.3, which was Aqua's update. The main coder did actually change 3 times (4 times if you include DC, who did it at first), which is part of the reason why there's now a tech update happening.
Last but not least I'm still not really sure what people actually expected from this specific update. They managed to add scenes for 3 very minor characters, giving each of them a bit of character and some background, while not breaking Nadya's character. That's all that was really needed if you ask me, given that they weren't ever supposed to get more than these few lines in the first place.
Next to that one should remember that Nadya and Jeb are actually real people from Russia/Ukraine and I'm pretty sure that Jeb actually helped with parts of the dialog. As said above, there may simply be some cultural differences at play in some details, which make it harder for people form western europe or even the US to appreciate it.
