Managed to solve this issue by reloading the game a few times, until it suddenly, without any reason started working. Weirdly enough, there is no talking to randvi and looking at map part, as it triggers a longer cutscene and forces you to do some main quest after that.

So just a warning to those who may experience this issue.

This helped me, many thanks.

Sadly, another bug appeared right after finishing this cursed quest. And this one is truly game breaking as it doesnt allow me to move, and do pretty much anything else.
After finishing the 2 main quests to pledge with the two out of three sides and finishing the Wise Friend quest, it tells me to talk to Randvi and welcome that new kings son to your clan. I proceed to talk with them and welcome him, this quest marks as finished, and right after that it says Pledge finished (or sth like that) and Randvi tells you to go with her and take a look at the map, and thats the moment where I get stuck in the dialogue/cutscene thing, cant save, cant move, cant interact, nothing happens at all, the game goes back to the "free roam" but im just standing there, stuck. When i quit to title screen and start again. Everything i mentioned happens the same way. I tried skipping the conversation, same issue...
