if it's intended I hope devs overthink this "feature" because it's super annoying when i build a swamp base and go the extra mile to build a pier like 80m from shore to secure my ship and some draugr with a bow just walks towards it underwater and destroys it while im gone.

I don't get why all mobs must be able to swim at all, i get its hardcore but damn i hate to come back to my base only to find my ship destroyed its not even fun, its just a drag and a giant f u to the player imo
