Confirmed in 15w51b, horses (and donkeys) will not climb up blocks while on a leash. Other passive mobs (sheep and pigs at least) have no problem walking up one block at a time, but horses will not. Thanks to this issue it is effectively impossible to lead a horse anywhere except short distances using a lead.

Joshua Cantrell 2016-01-13T20:24:40Z

Yeah, accidentally duplicated this one also - donkeys with chests are essentially worthless with this bug, as they won't follow you if you go up at all (which is inevitable, most likely)

This is still a problem in 16w02

Confirmed for 16w06a. Tame horse. Attach lead. Horse will follow, but not climb 1 block while on lead. If pulled, lead will break.

I can confirm that cows, and chickens do follow and climb 1 block terrain with leads. The problem is just with horses.

Julia Spencer 2016-02-15T21:29:24Z

Tested for 16w07a - Still an issue.

Created new world then tested on Tame Horse, Untamed Horse, and Donkey. They will follow, but will not climb full height blocks as per bug description.

Before creating a new issue, the one I've experienced may be related to this one. Horses don't have to be leashed to not climb blocks. Horses by themselves and in the wild won't climb blocks either while roaming around. I've kept my horse in a one-deep 3x3 hole for months and it never escaped. I've captured a few skeletal horses and threw them in a one-deep depression at the foot of a hill. They never escaped out of it either.

If not related, I'll create a separate issue for it.

Yup, MC-95973.

@redstonehelper

Oh! Thank you.

Joshua Cantrell 2016-02-20T17:59:25Z

Still happening in 1.9 pre2

Heriberto Rodriguez Jr 2016-03-01T00:29:06Z

Confirmed for Minecraft 1.9 sadly. 😞

Jan Urban 2016-03-02T11:34:07Z

[1.9 vanilla] neither do Iron Golems on the leash. Cows, cats, dogs climb 1 block tall inclines fine.

Rebecca Meyers 2016-03-06T16:54:43Z

If I put a slab in front of block can lead horse up block. Baby horses climb great. Still an issue. Thanks.

Michael R Jones 2016-03-10T20:21:42Z

Still not fixed as of version 1.9.1 Pre3
Horses being lead with a lead are unable to travel up hills and elevations 1 block high.

Julia Spencer 2016-03-10T20:44:56Z

Michael, do you mean 1.9.1 Pre2 perhaps? I wasn't aware that Pre3 was out yet.

I did create a new 1.9.1. Pre2 world and can confirm that the Leashed horses don't walk up full blocks in this version.

This issue really impacts gameplay with horses and more so with chest equipped donkeys and mules. I do hope it is corrected soon.

Michael R Jones 2016-03-11T07:20:44Z

My bad, I apologize. Corrected update: Minecraft 1.9.1 Pre-Release 2 affected version.

Julia Spencer 2016-03-11T20:40:58Z

Tested again in Minecraft 1.9.1 Pre 3. Issue still present.

Changes to pathfinding code in Pre 3 did not seem to affect this issue.

Michael R Jones stated that the issue first appeared in Snapshot 15w40b. (See duplicate: MC-98304)

I can confirm that - I tested 15w39c, and horses with leads worked correctly. I did the same test under 15w40b and horses with leads do not work.

MOD: Could you please append the description with:
"Issue first appeared in 15w40 snapshot"

I think that information would be helpful to the developers.

Lucas Kempen 2016-03-22T16:14:31Z

Horses cannot walk up 1 block leashed or unleashed. Snapshot taken on Minecraft 1.9

John Peaden 2016-04-01T23:56:42Z

This is an annoying problem in Minecraft 1.9. It means that you can't effectively take multiple horses back to your home base. Nope, you've got to tame them and ride them individually. Literally shocking. Horses will also get stuck at the lowest point of land, like in rivers, if other comments are to be believed, but I haven't noticed it. Good thing we have an april fool's update though. :/

Rebecca Meyers 2016-04-02T06:32:32Z

In order to get around this annoying bug, if you put half blocks down, the horse will move up quite nicely. While it is time consuming, you can get your horses, on a lead anywhere you want to go. Half blocks of anything works. They will also move up half blocks alone too.

John Peaden 2016-04-02T21:38:02Z

Thanks for the suggestion. I have noticed they are also capable of climbing out of water. I guess because of the "boost" it gives you. So they can exit a river, but they always stay at the bottom level. At least it is therefore possible to take horses across rivers with leads, but you can't do much else, unless you carry half slabs around with you.

Jan Urban 2016-04-04T11:56:17Z

as of vanilla 1.9.2 automated update, horses nor golems travel full blocks up. problem persists.

Julia Spencer 2016-04-11T20:29:40Z

Confirmed in snapshot 16w15a

The changed pathfinding code had no effect on this issue. Tested with Horses and Donkeys in new world.

Stardust 2016-04-18T02:19:17Z

I just found out the weirdest thing. So I had looked this problem up after I experienced it myself, and I found this. The weird thing is, just now I decided to lead an adult horse and a baby horse just to see if anything has changed- And I'm curious if it's the same for anyone else...Baby horses can climb up blocks. At least the one I found can...

Stardust 2016-04-18T20:39:57Z

Same thing for baby donkeys...It appears as if the problem is for the adults.

Julia Spencer 2016-04-21T22:45:09Z

FYI - this was fixed when the parent issue MC-95973 was corrected by Prof. Mobius / Thomas Guimbretiere. (Thank you Thomas!)

I've re-tested both cases using horses / donkeys with different terrain configurations in north-south, and east-west directions with and without leads.

The changes in 1.9.3-pre1 have corrected both the general pathfinding issue, and this more specific issue of leading horses / donkeys using leads.

Rebecca Meyers 2016-04-22T00:11:06Z

Thanks for all your hard work!!

[Mod] redstonehelper 2016-05-10T11:29:43Z

Actually fixed in 1.9.3-pre1.
