Now i've noticed this in game before the mod
but swings are not matching to where they are hitting, hitboxes are wonky in this game
you can have 4 inches of your blade go into an object but it doesn't register as a hit.

I think the katanas are suffering from this. Mine has 97 length
I watch the blade hit my enemy but I get no hit registration at all unless i'm closer to them
"I.E the blades hitbox is shorter than the physical blade"
