Before:

• Tittle: The caves generation have been changed and now the caves dont generate big lava lakes in y= -54 or is very rarely to find it
• Description: In this generation change, the world change too, but now the lava lakes dont generate or very rarely it generate.

After: Searching large lava lakes, I saw that the generation of large caves can't reach Y= -54, not allowing to generate large lava lakes. Compared with the version Pre Release 5, that this lava lakes can be generated

Now: Searching large lava lakes, I saw that the generation of large caves can't reach Y= -54 because the generation of large caves increases in height a little, not allowing to generate large lava lakes. Compared with the version Pre Release 5, that this lava lakes can be generated.

Sorry if my english is a little bad
