So the recent patches fixed a lot of stuff, but there is still some errors and inaccuracies left. A lot of screenshots here, so I put it under spoiler.
Summary
First of all, big problem with Yurgryn. It seems translators apparently didn’t realize she was a woman. Therefore, all dialogue with her is written in the masculine gender. When I saw it in very first time I thought what Crate become woke or something 
. I hope it’s not the case.
Some examples:
And much more. Needs to check and fix all dialogue options + also her lore note - Dreams of Ruin, needs that fix too.
Grisha - typo in dialogue text:
correctly: “тёмному богу”
Beorl (boy in Kurnhold) - also misgender:
Lokhor’s Madness set - tag missing:
Also may be the same with other sets, needs to check.
Main menu - full text didn’t show in the window on Veteran, Elite, Ultimate and Ascedant difficulties:
Also Ascedant translated as “Вознесенные” - why is plural? “Вознесенный” would be better.
Issue with Sorkar Saga - for some reason translator mess with titles. So instead of “Сага о Соркаре - часть 1” and so on there is wrong title for every one of them and there is no order in:
Now about text of this saga. Demon Vor’Suthul translated as “Вор’Сутул”. Emmm… How to say that correctly what people from English-speaking culture were able to understand… Ok, it’s sounds a bit funny in Russian. Like “вор сутулый” (thief the stooped - nice nickname for some Cronley gang hero btw). So in order to avoid undesirable connotations with criminal boss nickhame or whatever I suggest to rename it into “Вор’Суфул”. It may be not perfect, but far better then “сутулый”. 
That’s all for now. I hope it helps.
