The story in Morrowind is somewhat disappointing in regards to the fact that you can only achieve one ending, unlike Daggerfall. True the expansions add to the story and the end of one story pre-empts another, you can't escape the fact that the main storyline is too linear and might've benefitted from some degree of choice.

Nice to know there's a few mods out that let you side with Dagoth Ur and therefore creates an entirely new, if not saddening, ending.

The only notable bug I've found in Planescape that the fixpack doesn't fix is that the harlots in the upper east part of the Hive (the area you enter after emerging from the mortuary or the tomb) aren't properly classed as being harlots. This makes it impossible to unlock the harlot NPC entry in the journal when you first talk to any of the harlots in that area and you have to talk to a harlot in another part of the hive to unlock the entry.

I was playing the unfinished business mod with the fixpack and tweak mods installed. However, I don't believe any of these mods are the problem since I don't think either of them affect the harlots in the upper eastern part of the Hive.
