This vanilla dwemer chest spawns a key inside, which is definitely out of context. Hlan Oek, Western Sewers.

This piece of sewers set sticks out from a wall in Hlan Oek, Western Sewers.

These two sacks in Hlan Oek, Estoril's House scaled down to the maximum and look weird. It's best to restore their scale to 1.0. And while you at it, maybe you could remove this stack of crates (in yellow) for the House for Sale quest? An Altmer NPC should be put in that spot.

This graffiti is floating half a foot off its surface. The house is on the southern edge of town, near the water.
