1.13: Farmland doesn't get hydrated (seemingly randomly)

[OverCrave]

What behaviour is expected:

Farmland within the vanilla reach of water to get hydrated.

What behaviour is observed:

Farmland not getting hydrated in seemingly random patterns.

Steps/models to reproduce:

Should be self-explanatory.

Plugin list:

None, tested on a 'fresh' server.

Paper build number:

Paper version git-Paper-"4608731d" (MC: 1.13) (Implementing API version 1.13-R0.1-SNAPSHOT)

Anything else:

Like I said, this was tested a fresh server without any plugins. Testing in vanilla revealed that this is not a problem in singleplayer. The Paper version used was compiled with Java 10 and the server run with it aswell. I will include a screenshot of the test result.

What is your /gamerule randomTickSpeed ? Try increasing it for debug purposes.

I set up another fresh Paper server and tried just making farmland like in vanilla to test again. Was still there. Then I put the latest WorldEdit dev build on to test on a larger scale. I made what is shown in the attached picture. What is weird is that testing revealed that no matter if the randomTickSpeed is 3 or 1000 it always ends up in exactly the same pattern.

I tested it the exact same way again on a Spigot server and it works just fine on there, so yeah, definitely a Paper issue.

is this 1.13 only?

[OverCrave]

Considering I had a 1.12.2 Paper survival server where no such bug was reported I would say so, yes.

[aikar]

Ok just needed to confirm scope of if its a bad patch apply i.13, or longer term bug

[OverCrave]

Just to be save I tested the same way on the latest 1.12.2 build and yea, definitely 1.13

I've been having the same problem and it seems like it is a regular pattern of a line of hydrated farmland 4 blocks to the south of water sources.

[OverCrave]

Following up on Everett1999's answer I decided to test it like that on a larger scale, the result is in the screenshot. Again, redoing it always produces the same pattern.

[OverCrave]

Okay so it seems like the only farmland getting watered is the south-most side of the water radius, no matter the position. I'm gonna play around with some settings to see if something has an effect on it.

[OverCrave]

Playing around with paper.yml didn't reveal anything, that's the end of my testing abilities.^^

Fixed in build 34
