Still present in 1.14.3 pre-release 2.
the keybind for commands will always put a slash as if you were starting a command
1) There is a bug that has reduced iron golem spawn rates in villages.
2) 1 iron golem will always spawn in a village, but only when the village is first generated.
The trident issue that you say this duplicates has nothing to do with the trident issue I am reporting and nothing to do with the arrow part that I did duplicate. The tridents are turning black for reasons similar to why armor stands turn black inside of blocks, but without actually being inside a block. The trident issue that I am reporting is exactly the same reason as for the issue with the arrows.
The crash has nothing to do with the issue. If you go from windowed to fullscreen or fullscreen to windowed while the game is still loading, all mouse input for the game is messed up, and it requires at least a double click for clicking to register. This includes clicking menu buttons, interacting with your inventory, and left/right clicking to use items and place/break blocks during gameplay.
Invalid. Wrong project. Should be reported under mojang web services.
Works as intended. Cats and ocelots are separate mobs now. To get tamed cats, you have to tame stray cats that spawn in villages. Ocelots are no longer tamable. You can feed them to make the trust you (meaning they won't run away), but they can still do what they like.
Invalid. Non-vanilla environment.
I would say works as intended. They can spawn anywhere with in 48 blocks of the player.
This works as intended.
Bubble columns only generate in water source blocks.
Items aren't just pushed down one block. If there is a solid area under, the item gets pushed down until it hits an open area.
Using google translate, this looks like it is actually a duplicate of MC-143351. They are trying to place maps (in item frames).
Naturally spawned wandering traders despawn after 2-3 in game days so there isn't really a point in the trades being able to be refreshed b/c they disappear pretty quickly anyways. However, I do think that you should be able to do more trades with them before they are locked out.
I would say this works as intended b/c scaffolding can't occupy the same block as the one it breaks on, and it can't float above them. Also, if it was changed, it would be inconsistent with other falling blocks.
Still in 1.15.2 except the scores won't update at all in either book (following steps to reproduce).
