The last posts I saw about this were in Summer 2020. I am having this issue for the first time. Some NPCs don't have voices, which is difficult when they are speaking during a battle and I'm missing clues. (These are quests I've played before, so I know someone is supposed to be talking. Tried turning on subtitles for NPCs, but none came up.) Didn't see any answers posted to the 2020 thread. Is there a fix? Relogging, repairing, etc. have not fixed the issue.
