Led animals cannot jump up 1 block

It seems animals will not jump up one blocks when being led, but have no problem when on their own. Confirmed.

Hostile mobs also display same behavior when pursuing. I had an archer that could not go over 1 block, he just bounced.

I can confirm this too. Been doing so good playing these snapsahots, finding only minor problems until this one. I cannot even get a cow, sheep or anything else into my base.

This better get fixed before the update comes out.

confirmed with OS X Mavericks, Java 7 Update 55

Cow, pigs, and sheep can't seem to jump over 1 block 1 obstacles. Chickens however can.

Confirmed on OS X Mavericks, Java 6 update 65 on the 14w31a snapshot.

I have seen the same issue with chickens not following me when I have wheat seeds in hand. The chickens will go into love mode if I feed them (right click). The chickens simply flap their wings and act like they are trying to hop up a single block. I have seen this most often when the chicken is in the water trying to jump up onto dry land but I have also seen it happen on dry land.

There appears to be a general problem with chickens following me for any distance when I have wheat seeds in my hand. They will simply stop and refuse to move towards me on either dry, flat land or while swimming. It appears that I have their undivided attention but they simply refuse to move towards me. No monsters around or anything like that. This was the issue I was going to submit but chose to not duplicate MC-64497 and comment here instead. I have yet to try leading any other animals.

I am running single user mode with cheats enabled (for flight in creative mode) on 14w31a and I am not in creative when I experience this problem. Pretty much a vanilla MC 14w31a system running under Windows 8.1 on an ASUS gaming laptop.

I managed to get one chicken to follow me by pushing it along in front of me. This took way too long.

My present work around was to go into creative mode and grab about 3 stacks of eggs and shoot them against a cobblestone pillar inside a fenced area.

Talk about a game stopping bug. Hope it is fixed post haste.

I'm also seeing this behavior in 14w31a, with cows and sheep. My work around is to use slabs to make steps that they can climb.

Confirmed in 14w31a. Observed with passive and aggressive MOBs, but not 100% of the time. What happens is sometimes the MOB gets stuck and is unable to climb up a 1 block high gap and will stay there jumping. Have seen this with led animals including sheep and pigs and with aggressive zombies following a player.
