Mounting Beefalos shouldn't be repeatable

Technically not a bug but there's no reason for this to be there and that has been a considerable, consistent annoyance :

When mounting a Beefalo, if you dare click before the full animation is over, the character is gonna attempt to mount over and over. Getting on takes quite some time so I tend to click to move only milliseconds before, thinking I could move, then I find myself stuck for at least a solid second.
