Horses, yes those things the new people use. Not my point...

Horse bugs..

Horses go swimming on docks and ships. When the should be standing.

Hold Q and you can make your horse SLIDE accros the map (all terrains: water, snow, sand).

Pegs dont work after a bit of time, this is hte thrid time I had to collect the peg and go to my horse half ways across the map. This makes it difficult to feed it when your away.
