Marlene (TR_m3_Marlene) from the Drinking, Stealing, Ranting quest (TR_m3_Rd_Drinkstealrant) doesn't disappear from the prison cell after finishing her quest.
As said above, at the Imperial Archaeological Society's basement one of the common interior pieces is just missing at the dining area. Seems somebody might have accidentally deleted it.
Went inside Runat, killed all 4 Tusks inside cave (Rathys, Feril, Vanu, Nalmen), freed the slaves afterwards, then went out of cave and killed Adresu on top of the hill. Quest after this did not progress to the next stage and is eternally stuck at the first stage.
Simple one, Lanette's corpse doesn't persist. That means if you kill her, then get tasked to retrieve her sword, you can lock yourself out of that quest.
The basement exit, which is supposed to put you underwater, places you above the exit, inside the Almas Thirr bridge structure, if they player has a Water Walking effect active.
In the exterior cell Varashimmus 6,-35 in the Andaram release there is an exterior static piece - ex_dae_ruin_04 - with ugly exposed faces at eye-level. CS and in-game OpenMW screenshots provided. It's hard to get an angle on it in the CS, but you can see it in the in-game screenshot at the center-right. This appears to be a problem with a Bethesda asset: the edge of the weird half-pipe is a pixel wide when viewed from the side, suggesting it wasn't meant to be visible to players or sunk in with rubble. There's also a gap between where the weird dome face ends and the ground.
