Java Edition 1.3.1/List of broken features

This page details features which were broken by 12w18a's client-server logic split which remained broken into the full release of 1.3.1.

Ghast loading animation
When Ghasts were first added, they would expand slightly before shooting a fireball, similarly to a creeper about to explode. This created the effect of the ghast "charging" a fireball, rather than just opening its mouth and firing it. However, the effect was not properly networked from the server to the client, causing it to not work in multiplayer. As a result, when singleplayer was changed to use an internal server, the effect broke there too. The expand code was removed entirely in 1.8.

Directional damage tilt
Originally, taking damage would cause the camera to tilt towards the direction the damage came from. However, the direction value was not properly networked from the server to the client, causing the camera to always tilt left in multiplayer. As a result, when singleplayer was changed to use an internal server, the directional tilt broke there too. This was reported on the issue tracker and very controversially marked as "Won't Fix", though the (broken) code remains in the game to this day.

Progress bars
When generating or loading a world or entering a given dimension, a green progress bar would appear on screen under relevant text. This no longer appears. For world generation and loading this was effectively replaced with a chunk graph, but dimension loading screens still show nothing.

Dimension text
When entering the Nether or End, the screen would respectively display "Entering the Nether" or "Entering the End". Leaving either dimension would display "Leaving the Nether" or "Leaving the End". This no longer occurs.

Saving Level text
In the pause menu, the bottom left would display "Saving level..." for a few seconds as it saved the level. This no longer displays, despite entering the pause menu still saving the game like before.

Minecart physics
Prior to the client-server split, minecarts were capable of pushing players, and would react immediately and change direction when pushed. However, minecarts no longer push the player, and turn very sluggishly.

Nether portal exit animation
Exiting a nether portal originally showed a screen effect combination, in which the nausea effect would ramp down and stop and the overlay would disappear. This no longer occurs since 12w18a.

As of 12w34a, the nether portal screen effects and trigger sound will play even if the player arrives on the other side of a portal, making the brokenness of this exit animation hard to spot. It is still noticable given that this wrong animation starts weak and gets more intense as if this were a newly entered portal, rather than beginning at full intensity.

Portal travel sound
Travelling to another dimension via the use of a nether portal would result in a dedicated sound being played on the dimension loading screen. This sound played as expected up until 12w18a, when it stopped playing completely, teleporting the player silently. In 16w02a, this sound would now play again, however after transport to the dimension rather than on the loading screen.

Several particles
Certain particles were created dependent on the server, and never showed up on clients connected to said servers. As a result, several particles simply stopped appearing in 12w18a and beyond. The majority of these were eventually fixed in 19w14a.

The following particles stopped appearing in 12w18a:
 * Particles from redstone torches burning out
 * Bursts of particles from successful breeding
 * Active particles from animals in love mode stopped appearing in 1.9, for a likely similar server-related reason.
 * Particles from mobs created by spawners
 * Particles from contact between water and lava
 * Particles from placing an eye of ender in an end portal frame
 * Particles from creating snow golems
 * Particles from creating iron golems
