MC-15548Breeding mobs from far away in creative client-server desync
Fed two chickens some seeds. Both showed hearts. But they didn't actually more towards one another even though they were within horizontal range. (Initial vertical range was 3-4 blocks, I estimate.) Luring them together with seeds didn't help. Once they were standing practically in the same block, I switched away from seeds to some other hotbar item, but they still ignored one another. See image; they're adjacent, they're both emitting hearts, and yet they're still not getting it on 
After the usual delay the hearts timed out for both, I re-fed them and they bred OK on the second attempt. I've never seen this breeding glitch before.

Both emitting hearts; close together; not looking at Steve, (which confirms that Steve wasn't holding seeds at the time) yet still not breeding.
Even more annoying with wolves; if you feed them, they enter love mode, but you are feeding to heal.
And with cats... You right click, they make the hearts, but they are love mode hearts. You wait a min for them to finish, then you try to tame again, with no success, then you ragequit.
Unable to reproduce.
Wait, the issue I am thinking of is how animals with hearts refuse to take food.
This is a random glitch thing, nonreproducable.
Is this still a concern in the current Minecraft version? If so, please update the affected versions in order to best aid Mojang ensuring bugs are still valid in the latest releases/pre-releases.
(Automatic Message)
I encountered some more non-breeding animals, and perhaps a more reliable way to reproduce. Please reopen.
To reproduce, find a couple of animals trapped in leaves, very close to one another but not in the same block. Give them food, /then/ free them. I did this with a pair of cows, and as for the chickens they stood next to one another yet still refused to breed until re-fed.
1.6.2, BTW
I found a 100 % reproducible way: there are a number of reports about basically the same bug: interacting with mobs from far away in creative.
Client thinks he can reach the mob at certain distance, while server disaggrees. Client shows successfull interaction, server-side nothing happend.
Here aswell: get far away from the mob, slowly aproach it again with corresponding food, eventually you'll find a spot where chickens show hearts, but won't breed, since it's only client-side.
@tails
The main reason why that would break it anyway is because of a fix at some point that keeps you from being able to feed a animal twice.
The client thinks it is already fed, so when you step closer, it doesn't try again.
The server never says it happened.
