I suspect this comes up if you are trying to convert Bing's brother for Terjon as part of the Seven Brides for Seven other Examples of Poor Writing quest. Otherwise just talk to Bing's brother and see what he has to say. Not I, that sounds like a Temple+ thing. Sounds like they fixed the, "all NPC followers sneak if one player does" glitch.
Blindness/Deafness (the spell) has a duration of 1 day on the description, but the condition doesn't seem to go away on its own at all (just tried resting for a week, no effect). (Not sure whether that's an issue with Temple+ or Co8, @Sitra Achara ?)
No, I mean regular cure deafness dealt with it as well, so it's not big issue. I just thought it should be reported since the spell says specifically one day.
I also would report following issues: Soften Earth and Stone spell does not have adequate area particle, nor malus indicator; Hooting Fungi (lower Temple level 3) has strange blindness, with no indication how soon it should stop. It did removed itself after the encounter. Python error: File "scr/py00040hedrack_allies.py", line 80, in san_heartbeat; tuple index out of range.
Additionally - there was very strange Random encounter, where some Brigands have HUGE loot. It looks like some testing leftover.
