Is there more in the sewers beyond where Misha is? There's no sign there to indicate it's under development, but I can't seem to progress further; additionally, while I couldn't access the sewer from the map, I found a bug that scrolled through the map and I saw that there was a whole set of fast travel points for the sewer, including ones beyond where I found Misha. I want to know if the rest of it is still under development or if there is more already and not being able to progress is unintended.
