Can't confirm. A simple test using a scaled down version of Unarybit's villager farm showed no unusual behaviour; the farmer class villager (brown coat) harvested, replanted and shared food as expected. It should be noted that you cannot use this type of farm long-term with beetroot or wheat(bread) due to the farmer collecting both seeds and produce. Eventually their inventory will fill in such a manner that they will no longer attempt to share the produce with other villagers. This is by design, not a bug.

Tested in: 15w51b, Java 1.8.0_66 64 bit, Windows 7

14w25b - (Crappy work computer, shh don't tell) Windows 7 32bit, Java 7u55

Sorry about the crappy graphical glitches, but I'm at work and just wanted to test/show that slimes are def. spawning MUCH better this snapshot. This is a standard superflat, screenshot taken in less than one minute after loading the map. (Fresh map)

-----------

On the SMP Vanilla Snapshot server I play on, myself and another player successfully gathered slimeballs in swamp biomes at night. I managed to get 18, he had a looting III sword and gathered 74. Other players were able to find slimes as well.

14w25b

Same two tests as before:

Found a large swamp, set to night and flew around. I was able to get a couple slimes immediately, and after several minutes had several of them. No flickering spawn/despawning seen anymore.

Standard superflat, first slime spawned in seconds, and 4 more right behind him. In 30 seconds there were 14 slimes on screen and no flickering behaviour was seen.

It wasn't listed in the bugfixes, but it appears to have been fixed. Can others confirm?

Several minutes of testing in creative confirms this for me on 14w21b. Win7 64bit, Java7 u55

Tried traditional superflat. Slimes immediately being to spawn but instantly despawn. 5 minutes of hovering around yielded only 1 med slime that did not despawn, though he was gone immediately upon reaching 40 blocks of distance.

Loaded a new seed, located a swamp biome and set time to night. Again, slimes try to spawn immediately but instantly despawn. 5 minutes of hovering around again yielded only 1 med slime that did not despawn. 1 large slime spawned and remained as well, but was 40+ blocks away and despawned after 1 hop.

I play on a snapshot SMP server, and currently slimeballs are the most precious resource. I have yet to see or hear one in a week of play.

I figured Unbreaking III was possible part of the issue.

@Kumasasa I'm intending to try and replicate this as many ways as I can, but I have to point out that a sword most certainly does get damaged when you mine blocks. In fact, it takes more damage from mining blocks then it does from striking mobs, 2 vs 1. It has been this way for as long as I can recall and it is addressed in great detail by one of Xisumavoid's MythBusting videos.

Screenshots taken in rapid succession to demonstrate.

This is definitely still an issue. I wandered back to my home base on my private SMP server to use my skeleton grinder, and crashed down to 19 fps from my usual 120. 4400+ entities.

I've been letting people use the skeleton grinder and apparently they don't stand where I usually do. Breaking the blocks the arrows are trapped and allowing them to fall seems to permit despawning.

Vanilla server.
