This is probably the best bug report I've ever seen. Check your difficulty settings, they're only very powerful on Hard difficulty.

I can also confirm for 14w32a. Screenshot attached.

If you played in the snapshots, try reinstalling a fresh copy of Minecraft, that should fix the problem. Snapshots write newer versions of files than 1.7.10 can handle. Its advisable to have two separate folders for Minecraft, one for 1.7.10, and the other for 1.8 snapshots.

The latest snapshots cause this issue with older versions. This is because the snapshots write newer versions of the files than 1.7.10 can handle. A way to fix this is to reinstall Minecraft.

Changing to the new snapshots changes the settings of your Minecraft files. Going to a previous version causes problems because your files are a newer version.

This isn't a bug, it's always been like that. This is useful for hanging over the edge to prevent falling off.

There are new items that have been added to the snapshots for 1.8.
Resource packs won't work properly because they are made for previous versions, unless they are made specifically for the version you are playing on.

Make sure your selected version is the previous version you were playing on before switching to 14w30c. Deleting the download doesn't do anything unless you switch which version you want to play on.

Edit: You can only play on servers with the same version as your client.

This is a new feature for the upcoming 1.8 version of Minecraft.

Same here. The external server program helps this a little, but when the player moves to a world edge (unloaded chunks), the server program crashes. This also occurs with the internal server program in Minecraft, but instead demonstrates high lag.

Different instances of the same seed and coordinates result in different entity generation results. I have seen it when I recreated my previous worlds. Entities such as Cows, Pigs and Sheep are generated differently among the world with each recreation of the seed.

Isn't the server integrated into the game? If so, it should know as fast as it can generate chunks. If this case involves a client joining a remote server, then it would be a little slower, based on data transmission speeds.

Uploaded screenshots to help confirm this issue.

I can confirm this with my analysis of this issue. I'm adding the Development Console Log from my run of Minecraft.

I can confirm this too. I've seen it in the nether.

Confirmed for 14w29b.

This has to do with a 32-bit integer boundary. A 32-bit signed integer ranges from -2,147,483,648 to 2,147,483,647. Therefore, if you increase by 1 level, you would technically wrap back to -2,147,483,648. But Minecraft is programmed to set it to zero instead of -2,147,483,648, to avoid negative levels. This isn't a bug, it is simply a programming boundary with 32-bit, unless you move to a 64-bit Minecraft version, then it would range from −9,223,372,036,854,775,808 to 9,223,372,036,854,775,807, being a 64-bit signed integer.

Confirmed for 14w28b.

Confirmed for snapshot 14w28b.

Confirmed for snapshot 14w28a.
