I ran into something odd.
I loaded:
Oblivion.esm [SI]
Unofficial Oblivion Patch.esp [3.31]
into TES4Edit. Checked UOP for errors and found none.
Then I loaded:
Oblivion.esm
Better Cities Resources.esm
Unofficial Oblivion Patch.esp
Better Cities .esp [4.7.1]
Better Cities Full.esp
into TES4Edit. Checked UOP for errors and it returned the following errors:

As suggested, the teleport errors are probably intentional, but the quest target should point its target to the proper door.
My first mention of the issue was in the http://www.gamesas.com/index.php?/topic/1121078-relz-unofficial-oblivion-patch-320-unofficial-patch-supplementals/page__st__20 thread, post #34.
Hope this makes sense.
