A post in MC-119 has me running a test of both errors. Is anyone able to replicate it on an unmodded 14w07a? I have not yet.

Steven, I will leave a test build running since you mention this.

Is loading/unloading considered necessary? I'm fairly sure I can just stay near the chunk to get this to happen.

Ezekial,

Just last night, I was on a 1.6.2 server I host and a coworker and I were talking about how MC-2025 was not actually fixed (bug has thankfully been reopened) when him AND his horse that he was riding sunk into the ground.

I've seen it in Single Player as well. We use 64-bit Linux environments with Java 7.

So, it was not co-fixed with MC-2025 as [Mod] Kumasasa suggested as a possibility.

Confirm still broken in 1.6.2 Pre-release. Playing with Java 7 in Linux.

This image I uploaded is only chickens, but it has happened with other mobs that are less crowded.

I wonder if this is related to MC-119 since mobs and boats are both entities.

Paulquappe, I would call these the same sort of bug because mobs of any type are passing through materials they shouldn't... whether it is sinking in the floor or slipping through a wall. With the screenshot of the villagers, you'll note that they appear sort of dark/black-ish when embeded in the wall. This is the same with the mobs that are sinking.

In addition to sinking (most noticable) and passing through walls (careful attention required), mobs can pass through fences.

I had a farm of sorts set up and noticed the population slowly declining. It was most noticeable with colored sheep since they could be tracked. I engaged fly mode and moved around to find a bunch of the color sheep had "migrated" to another area 50-100ish blocks away. They were with, what appeared to be, some of the missing pigs/cows. I can't confirm them though - only the colored sheep. I culled that flock and rebred some of the sheep... and waited.

In "mobs passing through fence.jpeg" we see the sheep, with enough time, have passed right through the fence to hang out on the ledge they are not willing to fall from.

In addition to "sinking", mobs are able to pass through solid walls. We see in these two screen shots that the villager is starting to enter/pass through the wall. We also see one outside of the wall.

The villager on the outside of the box started inside. He couldn't jump over anything and passed through the cobblestone wall.

EDIT: In reference to images named: "Screenshot from 2012-12-31.jpeg" and "Screenshot from 2012-12-31 2.jpeg"

Not only does this affect Windows 64 bit and OSX, it affects Linux 64 bit environments as well.

I experience this on Vanilla and MCPatch'd Minecraft and only with minecarts. The visual issues have been resolved, but sound remains the same. It happens at all speeds - The faster I got, the more intense it becomes.
