So if you haven't noticed, I'm sorry as it may bother you anytime you're sailing from now on. In Odyssey when sailing, Ikaros would follow behind the ship. In Valhalla, your Raven, Synin, just continues to fly in circles above but in a glitched-out fast mode so you see him swoop past every two seconds at the top of your screen. The circling is fine while walking or on horseback, but it's really distracting and looks bad sped up when sailing.
Hopefully they patch this.
