In large caves, the cave generation can't reach y= -54, not allowing to generate large lava lakes
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























Can confirm
This is also making sharp borders in the caves from a Pre-release 5 world

It's rare to find lava in these type of caves now
Can confirm still in Pre release 7
Can confirm, hope this is a bug, I loved the large lava lakes.
Not sure how this happened since there was no mention of a change to this and it worked in a few of the previous pre releases.
Edit: Just thought i'd add screenshots to show comparison, its next to impossible to find lakes like these anymore
I dont know if the 1.18 release with this bug not solved
Shame this wont get fixed, I had a seed scouted out where a lava lake was the center of it. damn that sucks
Edit: ayy thank you mojang
I assume this was a side effect of the fix for
MC-241941which was supposed to only happen in the nether.Anyway good this is fixed now
Pls make the bug report like this for Bedrock
