The Morning Sun is a big quest hub in Hlan Oek. In one of the quests, the player is tasked with escorting a Redguard out of the tavern. But the mid-level corridor becomes an impossible struggle for an NPC (OpenMW). Aveno tried to fix the pathgrid, but the problem remained in my game (maybe a savefile issue?). In any case, it needs testing, or else The Passage to Menevia quest might become a major headache for the players.
