One thing I've always noticed on Taris is that the western apartments entrance door looks shoddy and seems like it belongs in the lower city.

When you go down to the lower city, the first apartments you come to directly across from the elevator have a pristine door that looks like it should be in the upper city.

Anybody ever catch this?

Huh, never noticed that. Will have to check that out next playthrough, sure it was just a mistake.
