Water doesn't flow correctly when there are "near" holes in ground

Water flow is affected by random ticks, leading to semi-random spreading speeds. Are you sure it's not just that?

I've picked it up, placed it again multiple times, tried different spots, and it only happens on Chunk Borders. It won't spread to the final 3 blocks where it should. It's not a matter of the tick rate.

If you re-create the world, does this always happen?

This has nothing to do with chunk borders or random tick speed, it's got to do with a bug in the "water flow checking" algorithm. Here's some screenshots to demonstrate:

Expected behaviour:

Unwanted behaviour:

I've placed down lapis blocks where the water should have flowed, but because of the two holes in the back, the algorithm thinks water should go down there.

So, my conclusion: Yes it's a bug, but nothing to do with chunk borders or tickspeed.

@Autom: In the images of the OP there are no holes in the ground.

@Kumasasa: Yes there are, on the left side of the screenshot, there is a whole row of "holes" 🙂 Let me add another screenshot, where i get the exact same situation where he has:

Here you go!

The same thing happens with lava.

There's also this bizarre circumstance. It seems to be a problem in where water checks for holes.

Confirmed for 1.8.2-pre6.

I am adding 3 pics (ones with bunch of chickens) of my problem. I am unaware if what is happening here is related to this ticket. I am currently in version 1.10-pre1 but I was first aware of this in 16w21b.

Is this still an issue in the latest snapshot 16w44a? If so please update the affected versions.

This is an automated comment on any open or reopened issue with out-of-date affected versions.

What's happening to me is still happening in 1.11.

Water is supposed to flow towards holes if there are any within a certain radius. 

I'm pretty sure these holes are out of that radius. Water shouldn't attempt to flow to somewhere it can't access.
