I've been following what I though was the northern border of the map for the past few hours in an attempt to meet up with my group. With the addition of these nifty party arrows, I decided to see if I was headed in the correct direction, but the arrow is pointing NW of me (into the invisible border). The way I see it, there are two possible explanations; either the map has some irregular shape that makes it seem like I'm at the northern border, or there is something wrong with the party arrows.
Here's a recording of my running against the border: https://imgrush.com/AXkGy_pvTepZ
Note that my camera is aligned with the cardinal directions, not the typical 45 degree angle like in the default client.
Anyone else experiencing something similar?
