How have you updated the game? Did you overwrite old files/versions with new ones, or use a fresh install, and transfer your save to the new version?
Terindus's event in front of the church doesn't have any other requirements other than him being alive, and not starting the quest "foundations", where you meet the priest in the bar. Romanos's first event in the commercial district also has no quest requirements, just that he is powerless, and you didn't kill him. His second event in Zerethin only requires that you talked to him in the commercial district, and completed the quest "foundations".
Sorry, I'm still getting the same error.
