I have a ton of entries in my quest log for completed quests. One is a companions quest, Animal Extermination in Grey Water Cavern, when I arrived the saber tooth cat was already dead. I can't get rid of this and then get other companion quests because they keep telling me I have an open job.

I have a bunch of miscellaneous "See Skald for your reward entries. He gave me the money but the entry never cleared.

I have numerous other nonsense items like this.

I tried closing the companion quest by getting the quest ID and entering the "completequest" command and while the quest disappeared from the log, the companions still treat it as an uncompleted job and will not issue any others.
