Hello, So I've had this problem every now and again for a long time now and I'm not sure if you're aware of it, so I guess I'll put it out here.
Ocassionally, my quest arrow will get bugged in that it always points directly forward. While in this position it will adjust the number of steps correctly, however it does not change direction and seems to be locked. It's not too big of an issue, except when it happens to someone that doesn't realize this is a problem so they keep heading straight and it's not always the right direction. It doesn't happen often, but hopefully it can be fixed!
