Search didn´t come up with anything useful - only a bugs during the quest Mightier than the Sword while my problem lies within the start of this quest.
So my problem is that I can´t even talk to the scribe in Uhziz - he is there but I only have the option to pickpocket him.
Talking to him is greyed out.
I tried to load a different save and to exit and restart the game - no luck so far.
Are there any known workarounds? I want to learn to read … lol 
edit:
Right after posting this I tried again - this time with mouse / keyboard and the option was there.
Not sure what the problem was or if it was the controller.
