@pokechu22 I put a list of affected mobs after the reopening of this bug (as of 1.14.3) in the description of this bug. The notable differences between the 2 lists (1.14.3 vs. 19w11b) are that the drowning issue for all (adult and baby) wolves, pigs, ocelots (not domestic), and chickens and adult domestic cats are fixed, BUT the issue of baby foxes and domestic cats are not fixed.

@hkniberg Can confirm that baby cats are still drowning even in the latest version (1.14.2 by time of this comment) This issue need to be re-opened.

@Kumasasa Can confirm that it has returned in 1.14.2 at least. Please reopen!!!
Also, make sure you reproduce the "fire" part of this bug in clear weather (not raining or snowing because they can extinguish fire)

A good tip to see this bug in action is happening is to "Toggle Perspective" (default key is to press F5) when an arrow is shot downwards to see the bouncing arrow on the player's head. This bug also reproduces when one is shooting an arrow at an angle toward the horse's neck (approximately), which make this bug extremely annoying for combat on a horse.

Please reopen this!!! This is reappearing in 1.13. Though baby animals seems to float on water (They will try to get to the surface), they are just perfectly submerged a little bit below the surface and it is enough to drown them)

Edit: Just found out and created a similar but not identical issue in 1.13: MC-134755 I confused that with this issue.

Adult mobs are not affected. It affects all baby mobs at all water depths

I found so many examples of this bug in the seed:
1903525598112592015
Coordinates in the end: 1683 84.5 -1204
and 1656 140.5 -1203

I can't reproduce it using boat in 1.12.1. But it can still be reproduced by riding minecarts/horses/llamas.

If you can't reproduce it, make sure the server has allow-flight=false in its server.properties file so it will kick out players in survival/adventure mode for floating longer than 5 secs.

This happens to ALMOST ALL end cities even in the most recent version: 1.12.1 Definitely still exists. I can hardly find one without the last slab at the wrong position

You should at least know a bit of java programming language to understand, such as what's an object, a class, what's extend or subclassing. NSObject.class is a class that relates java classes into objective C classes. I don't know much about objective C programming language, but at least I know it's the native language of macOS, and even iOS! The class NarratorOSX is a subclass of NSObject that implements the narrator feature of Minecraft in macOS.

If you don't know that much, you can just follow my fix by using the download link above and put it in the directory I've specified. Tell me if you get any problem.

See my screenshots in attachments above. Clouds can only be seen through slime blocks when the viewer's Y is greater than 128. See https://bugs.mojang.com/secure/attachment/141565/2017-06-17_14.53.09.png and https://bugs.mojang.com/secure/attachment/141564/2017-06-17_14.51.29.png

I have the same problem. On Minecraft Wiki Page Ocelot: http://minecraft.gamepedia.com/Ocelot It said that when spawned in creative mode, the player need to be more than 10 blocks away and then come back so an ocelot will sneak to the player and be tamed. However, when tamed incorrectly, it shows some heart particles and can never be tamed again in a long time and it looks like it loses its taming AI (will never try to sneak back again or run away)

I solved my Problem on my own! This is due to launcher not recognizing and downloading a library file "java-objc-bridge-1.0.0.jar". It is specified in 1.12.json and is only required for Mac OSX.(yet it is not a native library) As found in that file, the download link for it is https://libraries.minecraft.net/ca/weblite/java-objc-bridge/1.0.0/java-objc-bridge-1.0.0.jar The class com.mojang.text2speech.NarratorOSX extends ca.weblite.NSObject in which NSObject.class is in the missing library jar file. Put that jar library into the directory "~/Library/Application Support/minecraft/libraries/ca/weblite/java-objc-bridge/1.0.0" (without quotation mark) on your Mac OS X PC.

I've already seen MC-115725 that cannot be reproduced and is marked as resolved. My issue is for the released version, not any of the snapshot or pre-releases. I want to bring awareness to the Mojang team that this issue still persists in the latest version. Please tell me if I'm missing any libraries

I want to ask if a bug cannot be reproduced and is resolved, will Mojang never going to fix it?
