So far all works fine. Game is much richer on content.
Very minor quirk: during party creation, 2 extra skills do apply for all 4, and to avoid this, one must select them from 1st down to 4th, in exact order. Otherwise changes might apply to unwanted character (like changing 2nd skill to BOW for 2nd char will add bow to 3rd and 4th, overwriting their selection)
Other funky quirk: pressing F5 - quick save, leaves the viewing are like this (but it can be fixed by pressing ESC and then returning to game) https://postimg.cc/G9tN3fzS
