[Visual Bug] Model error on Nami's River Spirit skin

While this isn't a problem that effects gameplay or anything, I've noticed that River Spirit Nami's tail seems to be in a twist. It occurs on all of her general animations such as movement, but seems to be normal when using the commands for laugh, dance, or when recalling. It appears this way every time I see the skin in game.

Image Link I took some screenshots to show what I'm talking about. The left side is just walking (swimming?) and the right side has both the recall and dance animations.
