I've tested it and it is this mod specifically, and I have 0 clue as to why
-without the mod:

-with the mod

This also applies to other Horses and even Donkeys and Mules.

I've not seen it in donkeys and never tested mules.
But it's good to know, whatever it may mean.

There is another possible error with the speed of Zombie Horses and this mod. I uninstalled the mod, because it kept crashing my game whenever I tried to make a custom horde night or activate the other ones. They still move very fast, and I have no other mods related to Zombie Horses, except for one that just allows them to spawn naturally.

yes, that is what this ticket is about

I also have this issue.

Do you happen to have any updates on the issue? Zombie and Normal Horses move so fast to the point of them accidentally falling off cliffs or being able to escape fences and walls.

sorry, there seem to be no news on repair.
and yeah, horses move so fast they have difficulty actually doing anything.

Should be fixed as of 1.2.1a
