I'm still in a run that started before patch 4 and have some lags in Act 3, but fortunately not game-breaking. However I already encountered 2 broken quests in Act 3 : The Harper house that Jaheira brings us to doesn't have any harpers so that mission dies there, and Voss disappears from Raphal's room in Shares Caress and never appears in the tap room.
Wonder if these will be repaired also.
And unfortunately, in my current run I've let Shadow kill the Dame so she wants no hugs anymore. But I hope they put it in for maybe another PT later.
