What happened?

The left fin of the End Fish model appears to have its pivot point in an incorrect location. Rather than being placed on the outside of the body, it seems to be situated midway through. This issue appears to persist in the newest version of BetterEnd as well (1.21.1 at time of writing) and without any other mods installed. Furthermore, filling the entire texture with a single color shows that the bounds of the plane used to render the fin do not extend any further than is shown.

Expected behavior: Pivot point of left fin is in correct place.
Actual behavior: Pivot point is situated in the middle of the body.
