Bugged/decaying blocks and version issues

[Mario662629]

I noticed the following problems, at least for Java Edition:

• Some leaf blocks on certain tutorial worlds and minigame lobbies are decaying on newer versions of Minecraft. Watch leaves closely after setting /gamerule randomTickSpeed 1000. This can especially be seen with the jungle trees in the minigame lobbies.
• Some additional animals have naturally spawned in most of the tutorial worlds.
• In the TU46 Tutorial, some of the ice in the ice spikes town in the northwestern corner of the world is melted.
• In the TU46 Tutorial, there are columns of nothing but water at some locations (e.g. at X=98, Z=20 and at X=-149, Z=90).

Thank you for letting me know about these issues! While I am quite busy with life right now, I will keep this open and fix those bugs when I make the next round of updates. Cheers!

OK, I can show some proof now:
Melting Ice in Ice Spikes Town in TU46 Tutorial World:

Decaying Leaves (example from TU46 Tutorial World):
Before decay (leaves with distance=7 are brown to show that they will decay, using a resource pack):

After decay:

Broken/Empty Columns (example from TU46 Tutorial World):

Extra Animal Spawns (example from TU31 Tutorial World):

Also:

• Some spawn eggs in chests have fallen back. In this example from the TU31 Tutorial World, the wolf spawn egg inside the chest in the breeding tutorial area turned into a generic spawn egg on older versions of Minecraft. In newer versions, said spawn egg was a wither spawn egg instead.
  
• In some of the older tutorial worlds, like the TU14 Tutorial World, the oak slabs are petrified, when they should not. I have a resource pack active to distinguish the normal oak slabs from the petrified ones.
  
• In the TU12 tutorial world, the chest containing the mall music disc that is on a pirate ship in the northwestern corner of the world is missing.
• In the TU12 tutorial world, this tree next to this lava lake is on fire:

Wow, thank you so much for the detailed screenshots and info regarding these issues! It helps me out a lot. I'll attempt to fix everything you mentioned.

Just a couple notes:

1. It's a little hard to manage extra animal spawns since the game does this automatically, but I can check this before finalizing the world updates and make sure there's no extra mobs in the main tutorial areas.
2. The broken and empty columns are a part of the original TU46 tutorial world on the legacy console editions (I noticed this and checked). I assume it's from 4J's version of worldedit whenthey were creating the world and customizing the terrain

Thanks again for your help!

I checked the TU46 tutorial world on Minecraft: Nintendo Switch Edition; it did have the broken columns.

Also, another few issues:

• When running the TU69 Tutorial World in with Xaero's World Map on Fabric (at least when running the 1.13.2 map on 1.21.1), some of the blocks in the world map don't load properly until you temporarily create a solid ceiling above the top of the world using WorldEdit, selecting the top corners of the world, running //set [any block], and then //set air.
• Mob spawning can be disabled by making all tutorial worlds have /gamerule doMobSpawning false by default, although you can change it back later for the full experience in survival.

Thanks for the feedback. I will see what I can do about the Xaero's WM issue, but I'm mainly tring to make sure these maps work with vanilla MC.

I knew about the mob spawning gamerule, although that disables hostile mob spawns too. I didn't think this was worth it
