My character disappears when she uses the Rising Phoenix mount

[Eisi]

As stated in the Blog Post, it's working as intended. It's not really a mount, but rather a device turning you into the Phoenix.

Oh, ok, then I'm not gonna use the mount then .

Edit: It feels weird that my character turns into a Phoenix, like the devs didn't want to have them sit on it because it's too difficult to make work and so they resort to this.
