when I do afk horses, I dont know what happen, and then my character is stop, cancel AFK looping, and unridding the horse, but while im looking map, my wagon isnt there / when you find your wagon, you press "R" and this is happened "Your mount is too far away."

Because your Internet connection is unstable

Its casued by Dsync between server and your system. But I am also encounter the same issue especailly between 8 pm and 10 pm. and weekend . I think the server merge has casued the servers unable to handle high loads during node wars where half the server cap is going to node wars. And the other half have to cramp into V2 servers
