Main Quests, Following the Swimmer

Since these were last reported, it's been a year or more, so I'll bump up this here.

My "The Swimmer" which is supposedly a black horker, is actually a slaughterfish, and it can't get to it's destinations because it gets stuck on land. So the main quest is unplayable for this as it is.

I've only seen Boars, Bears and Wolves in bloodmoon as it is, and I've ran across the place. No spriggans, riecklings, draugr or anything (undead = skeletons and zombies so far), so I'm wondering if this is actually fixed long ago, and I just haven't found the download for correct creatures (or it doesn't exist). 

As it is now though, the main quest in Bloodmoon remains unplayable for me, and I'd like to see a temp solution (like can I "cheat" my way through that one ?). 

Thanks :)
