I don't even know what to call this..

We didn't have this option before, but now when you're on your horse, you can interact with NPCs, which is a good addition especially doing quest, saves you couple of seconds of dismounting your horse to interact with NPC.. however, this is becoming an issue in areas where there are alot of players standing in one spot, you can't get off your horse because it's the same button to interact with NPC/player (Y button). i think if you change the dismount to LB+Y it will make it easier..

this even happens when you reach areas where there is a gatherable item (harvest, butcher, etc) , you have to move away from the spot to be able to get off your horse..
