I really think that this bug is just a symptom of a bigger problem. Ever since the merge of single player and multiplayer there have been a few seriously annoying bugs that just never seem to get fixed.

• The mobs glitching as we have here.

• Players becoming separated from their boats. Which results in ghost boats and player images in multiplayer and boats that suddenly break for no reason but if you log out and in again you find yourself in a different position to where you thought you were and you actually just hit a squid or the tip of an island.

• The almost impossible task to hit back ghast balls which never used to be so difficult to time.

• Increased difficulty timing hits on attacking mobs,even worse for fast moving ones like spiders.

• Spiders yoyoing up and down when they are up at the ceiling.

These are just a few and I think the problem comes down to some serious sync issues between player and client that came about after the merge. It seems that the client and server are regularly at odds to the position of players. mobs, and other moving entities. It's gotten to the point where I adjust my gameplay to compensate for what I'm guessing the server is thinking.

I would also take a guess that the reason there seems to be no acknowledgement at all of a bug like this one (that is at the top of the list) maybe due to the fact that they are hoping to fix this problem with the new client when it finally is done.

I also can't help but wonder if on a high speed work lan and using top of the line hardware whether it's possible that these problems don't exhibit themselves as much, so it not apparent how discouraging they are for many players.

Right or wrong I dunno but I do know that since them merge some things have never been the same.

Nathan seems to be closer to the core of this issue than anyone and has provided useful input on many related topics. Considering how long this issue and others similar have been active, it appears it still is not assigned to a dev or even commented on by Mojang I'm happy to put up with a little spam. Stop watching the thread and bookmark it if it really bothers you.

I'm sure they are Brandon but you might notice that this ongoing bug is yet to have someone assigned to it even after all this time. Can't help but wonder if it is in the too hard basket or waiting on the release of the new client.

I'm surprised we haven't had a dev comment on this one by now. It's been hard enough to properly time an incoming mob especially since the separation of the client and server in SP and this bug makes it even worse for hostile mobs when it occurs. I'm tarting to suspect that they are leaving it for the release of the the new client to see what happens.

Regardless one way to duplicate it in SMP is to go to the end and go 128 blocks out into the void, then build a large triangular platform out of cobble that extends out for a further 64 blocks. Now build a diamond shaped cover two blocks above the platform in one corner. The cap should be large enough that when you place a water bucket in the center it spread to the egdes without spilling over. This is to ensure that the endermen don't teleport on top of the cap. You may also have to build a small room below the platform under the cap. Not sure if it's necessary but it is how I had done it on the MCD server.

Now if you stand under the cap and eyeball all the endermen that have spawned of the platform they should all teleport in to the base of the cap and bunch up. While you kill them off you should notice that they regularly fall into the floor of the cobble platform. Rinse and repeat until you have enough data on what is going on.

It's been common since 1.3 and affects all mobs hostile and passive. It seems to occur more often when there are blocks at different levels and especially when there are other Blocks and entities in the area.
Fences, torches, pressure plates, repeaters etc all seem to increase the chance of occurrence but are not require for it to happen.

I have also noticed it often happens to the player around redstone devices where there are a lot repeaters, torches redstone and blocks around. The game seems to correct the problem with a player very quickly, so it exhibits as the player bobbing into the ground and out again.
