Yes, I agree. XP gain should be linear, not exponential.
That doesn't mean levels should be easy to gain quickly though, the gap between levels should be reasonably large to make up for linear gain.

The chest is an end game item. There needs to be work involved in managing it. You can't have something of that magnitude without a huge downside. This was a well deserved nerf. The chest is fine with way it is right now, aside from a few balance issues in PvP.

And Silk Touch is not even close to the exaggerated rarity people are claiming. Especially with a gold pickaxe.

Coal and other ores still supply a huge about of exp, you can easily get to level 30 in a day if you find a good cave.

Chunk generation issues.

Basically, you know how every world you create is completely different? How the world is made is defined by the "seed" of the world. I'm assuming you've at least heard of Minecraft seeds and know what they do, but if not, check the link there.

Well, the seed for your world (along with various other stuff about your character) is stored in that level.dat file. If you replace the level.dat with one from another save file, it will change the seed to whatever the new file's randomly generated seed was.

When the game goes to create new chunks (which happens any time you travel beyond where you've already been) it uses the seed to figure out how to make the new areas of the world. If the seed is different than it was before, then the world can drastically change along the chunk boundary. Huge mountains with sheer sides next to plains, etc. You'll end up with areas where the whole terrain/biome/etc. changes along a perfect line where the new generation took over.

This can do things like cut villages and strongholds in half, and other messy things. It's mostly just aesthetic problems, but it looks awful.

Replacing the level.dat file with the level.dat_old file is the better option.

If you do what this poster is suggesting, the world seed will change (unless you typed in the same one as you did the first time) and very bad things will happen when you go to generate new chunks.


What happens when Minecraft doesn't shut down properly is that the "level.dat" file often gets corrupted. "level.dat_old" is the "backup" that Minecraft makes automatically. Replacing the corrupted version with the backup may still lose some stuff, but at least it doesn't change the seed (which has devastating effects on world generation, that you won't notice until you travel beyond where you've already been).
