"Gravelly Mountains+" biome has now modified_gravelly_mountains as ID, so its display name should be "Modified Gravelly Mountains".
"Block of TNT" entity is now named "Primed TNT", so maybe that one should be moved to MC-123540 to have its ID changed to primed_tnt
You could add that inconsistencies between names and IDs for those items :
leather_helmet, leather_chestplate and leather_leggings are named "Leather Cap", "Leather Tunic" and "Leather Pants" so it would be better that their IDs was leather_cap, leather_tunic and leather_pants
clay_ball should be named "Clay Ball" and not "Clay"
slime_ball should be named "Slime Ball" and not "Slimeball"
Still present in 18w10d
That's a problem from the website? 18w10d is actually released and I'm using it as you can see in my screenshot.
I didn't know that we can't take water with buckets in creative mode, sorry.
Maybe the "Primed TNT" entity should be added, because its ID is
tntwhich doesn't follow the display name.MC-124190 has that entity in its list but maybe that is the ID which should be changed and not the Display Name.
