Horse sounds lag the game upon dismounting

[chaoticidealism]

Describe the bug

When you ride a horse for a long time and then dismount, the game lags massively to the point of freezing, depending on how long you have been riding. After riding a couple of map screens worth of distance, I dismounted, the game froze for a couple of minutes; then I got a message that said "You hear footsteps. x1559952" and the game resumed.

Steps To Reproduce

Steps to reproduce the behavior:

1. Tame horse.
2. Ride horse for a long distance.
3. Dismount.

Expected behavior

Game shouldn't lag severely.

Additional context

[jeremyshannon]

Just encountered this in current experimental, toying around with horseback riding. Whenever I'd dismount he would zip all over the place in an instant, as if he had stored up all the moves that he didn't make when I was riding him.
I made a circle around a large city (which was fun, dodging zombies left and right) and at the end, off to one edge of the city, with no zombies in sight, I dismounted to see how many "you hear hoofsteps" events I'd get. Well, I guess he could see a zombie or something, because he ran. And I mean HE RAN, like to the edge of the reality bubble in a single tick. It was as if he had vanished from the ken of man. I couldn't find him.
Obviously horses have Time Dilation CBMs.
