@ubi-baron yes, no problems.

@atarav2016 during the conquest of Ledecestrescire with the Ragnarssons, precisely after speak with Tonna to find king Burgred.

@ubi-baron yes, no problems.

I don't know if it's a solution or not but it happened that after Cola disappeared he reappeared during the story mission in Ledecestrescire, after talking with Tonna to find out where Burgred is hiding. I tried to load and redo the missions from the beginnig untill that point several times and it always reappears, it is as if to reappear you have to take a step forward in the plot by changing the enviroment of the world or maybe it's just a case.

Same problem in a different way: i meet him but he was too strong and later he disappeared. He appears in the order menu but nothing happens when I track.  Just vanished. Do the zealots have magical powers?
