Bug description
Downloaded and installed the More caves No lava, More ores, and No mobs datapacks as instructed, whenever I went into the dimension my game crashed, causing me to be unable to access my world. May also be an issue with other datapacks.
When I used only More caves No lava, still crashed on my second visit (first was me hopping in then hopping out). It also had lava in the dimension by my spawn, so the datapack didn't work.

Steps to reproduce the issue

1. Install the datapacks
2. Create new world and add datapacks
3. Go to dimension
4. Crash, receive error code 0, and be unable to retrieve world

Expected behavior
Expected dimension to have more caves, no lava, more ores, and no mobs. Also didn't expect to crash.

Log files
Should be the crash log for ONLY 'More caves No lava'

EDIT: It doesn't work with just the one datapack, I did say but it's okay if it wasn't clear.
Not sure if it works without other mods, I uninstalled the mod so I can't say.

I need your logs.
Does it work with no other mods installed?
Does it work with just a single datapack?

Added logs, edited post.

The problem seems to be Mowzie's Mobs.
Can you remove that mod and try it again?
