Large slimes only need a height of three and small ones need two, so that isn't the problem. You are staying 24 blocks away to allow them to spawn, right?

The only way is to go slowly enough that it can keep up with you. Get in a boat and tap forward often enough to stay ahead of it.
Teleporting only works if the area the animal is in is loaded and you are close to land.

Obsidian is 9000 blast resistance, not lava.
This is what the wiki says about it:
"Normal Lava blocks are also resistant to TNT, and will not be destroyed by it. However, “flowing” lava blocks (those which are in the process changing their flow pattern, not those which display a current) are easily destructible by explosions; therefore, multiple successive explosions (changing the environment around the lava and causing it to flow) may destroy lava."

It is probably iron bars.

That is a square. It appears to be the same size as a chunk, apparently the lighting at chunk boundaries is bugged.

I think the more important question is since the moon is closer than the edge of the map, how can it orbit in the first place? It should intersect the map at dawn and dusk.

Try doubling the width and having two pairs of pistons come from each side.

Have the servers updated yet? You need to use the same version as the server.

i thought you couldn't get jungles without a map reset?

They changed that when they added the new map format.

I believe what you're seeing is the backup Jeb made the game take when it converts an older game save to the new map height.

That only affects stuff in the save folders. This is something completely different.

OP: Start minecraft and see what version runs. It could be that the updated files were saved to a subfolder instead of the main folder.
Don't delete the extra jar until you know what version it is, you might have ended up with a backup you can use with mods/servers that haven't updated.

Try searching the mod section of the forums for a downgrader, although I'm not sure how well they work.
I have a backup of my entire .minecraft folder for each version since 1.7. You should at least make backups of the minecraft.jar.

Also, this should probably go in the support section of the forums, not survival.

This should be the last time that happens. Biomes are now saved with the chunk, so updates won't change them in old terrain.

If you haven't done much yet, you could try starting a new world and seeing if it continues to do that.

Just a quick question: Would it be hard to give naturally spawned iron, gold and glowstone a different block ID to obtained iron, gold and glowstone?
...

It is possible. It wouldn't use a different block ID, but extra data that stores the color of wool or the type of wood/leaves. The aether mod does this with most of what it adds because it has tools that double the drops of certain blocks. The only problem would be when mining in old terrain: unless there was some kind of converter, the values would be random like old leaves after different types of trees were added.

I had seen some YouTube videos, so I knew how to craft. In the demo, I made a house with one brick wall and the other walls and floor made out of planks. It had no roof.
On my first real world, I built a brick house on a floating island. I eventually got netherrack, made the roof out of it, and set it on fire. That house was loud when it rained.
