 Description   

When using block.setBiome() or World.setBiome(x, y, z, biome) the block that is updated isn't in the same location as the one specified.

Here is an example of some dummy code used to test this:

Block block = event.getClickedBlock();
Location loc = block.getLocation(); 
loc.setY(0); // Set Y to 0 so it appears/updates in-game
loc.getBlock().setBiome(Biome.JUNGLE);

When a block is clicked, a different area of the chunk changes biome. For example, when clicking the blue carpet in the attached image, the biome changes in the area that's circled red.

I have attached a plugin that replicates this - if you right-click the ground with a stick it will change the biome to Jungle.

Please reopen the issue @md_5. This is not fixed. I've just tried with a fresh build of spigot 1.15.2 and its still not working correctly.
I've tried both  " world.setBiome(xpos,zpos,Biome.RIVER); " & world.getBlockAt(xpos,world.getHighestBlockYAt(xpos,zpos),zpos).setBiome(Biome.RIVER);

None of them work correctly. Dependign on the location sometimes you change the biome blocks relatively close to xpos zpos, but in a really measy way (changing one block may change 10, and distributed in a random shape (not squares), and sometimes i can't even find the change by walking arround.

All the tests have been done reconecting after the changes, and some even shutting down the server and starting it up again.

Thank you @md_5 for fixing this. I was having issues with it in a plugin but I assumed it was a vanilla issue due to how they changed biomes.

No problem, let me know if it is not fixed (it should be)

I just want to use this opportunity to say:

a) Sorry, didn't realise!
b) You are amazing, thank you.

Update your server to the fixed version....

As this issue has been marked as resolved, could I at least get some commentary as to how to work around this issue? I know biomes aren't per-block in 1.15.2, but it would be nice if I could even get close to painting the selected block.
