[KCD2] How to get to main level 30?

I am stuck on main level 29 and im at 93% it is not going up. I have done the entire main story and all of my stats and skills are level 30 except blacksmithing prestige. I have read that i need to do side quests aswell to level up my main level but i have now gotten an achievement for completing most of the games content and my level percentage is not going up. How do i get that last 7%?
