Sometimes a horse tethered to a fence with a lead will disappear/despawn, leaving behind the image of a lead. The lead does not drop when broken. The horses have done this in several different places, but all were named and saddled. This is on a private server, and has happened to one of the other two server members as well. One of the horses was in a 5x5 fenced area. The last incident happed at 1333 70 622 on seed -1944943543, the others were near spawn.
