Dude, vertical slab is not a thing (even though I wish it is)
a1.0.16_02 is too old
This is interesting, I was search for dupes and I found a lot of bugs that talk about raiders spawning in caves. But surprisingly, the only bug is "official" is MCPE-45183, which is in a different project and still open. Other bugs were closed, either a dupe of MCPE-45183 or were resolved as "Awaiting Response" or "Invalid". Here are all related bugs that is in the MC project: MC-237304, MC-233131, MC-223874, MC-184202, and MC-180703. Even more surprising is before this bug exists, the latest Java bug that talked about it was MC-237304, which was way back in 1.17.1 !!
If you know you have the same issue of REALMS-11621, then why on earth you have to make a separate report for it? Instead, just comment on REALMS-11621 that you have the same issue.
Invalid as it's a technical support issue
Please give me a video
I'm having trouble trying to understand the issue. Since I have zero knowledge about worldgen datapacks, and the reporter is inactive, could somebody explains what's the issue about and also explains what's "3D biome" and why "Multinoise does work right with 3D biomes and why "Multinoise does work right with 3D biomes" is considered as a bug for the reporter?
Invalid, modded game + not in English
Sorry, your issue is incomplete
Your issue is about 2 different issues. One is the joining server problem, another one is the skin problem, which already be tracked at MC-101579.
Invalid (or Duplicate) because of multiple issues in 1 issue.
Cannot reproduce
Please provide a log file of the game session the axolotl despawned
Brain, I don't think you need an underground village for the rail to spawn on the dirt path in normal generation. Yes, mineshafts can only spawn underground but that's only true for normal mineshafts. Mesa mineshafts on the other hand can spawn on the surface, so you don't need an under village. All you need is a non-desert village to spawn in the boundary of a badlands biome (since cannot spawn directly in badlands). Then a surface mesa mineshaft spawn near that village, which then a rail can spawn on top of a dirt path.
