There is a questline that was accidentally left out of the final game due to a misnamed file. "A Test of Determination" is a questline for the Vampire Clan where the given objective is to confront a Daedra in the local dungeon where it lives over the control the player's bloodline has in a given region. The binary file is named P0B1XL08.QBN and the text-file is named P0B10L08.QRC. As a result of this oversight, the player can never get this quest unless you change the name of one file so that it matches the name of the other.
