Critical bugs found in version 1.2.0.2

Below is a list of bugs in version 1.2.0.2 BETA 1:

1 - The Ghast when opening the mouth to attack executes its sound repeatedly (Bug).

2 - Charging chunks are locking many devices with similar versions.

3 - The game takes a long time to open your home screen.

4 - The inventory, even organized, should have the box of recipes only in survival mode.

5 - The blocks are invisible for a few seconds when we break or put them.

6 - The jukebox is not playing the discs.

7 - There should be more audio options.

8 - For some reason 1 hit equals 2 damage (Minecraft PC is 1).

9 - Fireworks with lots of mixtures bug the screen completely.

10 - It is still possible to duplicate items using a chest and two players.

11 - The option that activates the main java resource causes a lot of lag.

12 - Command_Blocks cause too much lag in repeat mode for any command.

13 - When we put blocks there is a delay of a few hundred or second to appear.

14 - Type 1 of the fireworks is too weak to fly with Elytra.

15 - The hint messages that appear when the world is loading pass very fast.

16 - In the chat there should be more options, like Gamemode, Playsound / Stopsound, among others ...

17 - When there are other players in LAN the game laga much more. Mainly to load the chunks.

18 - Skins take too long to appear.

19 - The store is very lagged.

20 - There is an error in the display of executed commands: In minecraft PC, if we give an effect, does not appear '' Given x seconds of x effect. ''. Please take a look and compare.

This was the list of bugs I found. Admittedly there are a lot more bugs besides these, but I would like these ones corrected first. I would like to participate in a beta system more closely and interactively with the developers.
