[SPIGOT-4775] Chunk Loading Errors on 3 Different Servers Created: 26/Apr/19  Updated: 26/Apr/19  Resolved: 26/Apr/19

Environment:

3 different servers:

1) Hosted on a minecraft host, upgraded from 1.13.2 to 1.14 using --forceUpgrade

2) Hosted on another Minecraft host, generated using 1.14pre5

3) A locally hosted server, using the map from server 2, running on maximum resources

Each server has 6GB of RAM and a fairly recent i7 processor, and resources on the servers are not being over utilized. The computer has 16GB of RAM, and a very new i7 processor as well. Multiple gigabytes free on each disk too.

The reason I used these three different environments was to check if the problem was persistent or if it was caused by a lack of resources/processing power.

Version: git-Spigot-47463c2-6de3aa1 (MC: 1.14)
Plugin: N/A
Guidelines Read: Yes

 Description   

Once spawned into any of these three servers, start flying in a straight line (direction doesn't matter) for about 500 blocks. As I start to go further and further from spawn (still only maybe 20 chunks away though in the screenshot below) the server starts to load chunks randomly.

Past a certain point on all 3 servers, the world would completely stop rendering or loading chunks,  but will render mobs still, leaving them floating in space above a void.

Max resource usage on the local server was about 20% CPU and 2GB ram, even while I was flying to new chunks.

The picture is maybe 200 blocks away from spawn, and if I sit there for a couple minutes the chunks won't start loading either. I also included a video of the specific phenomenon if you need, but hopefully the screenshot below shows how significant the visual errors are. ESPECIALLY THE VIDEO.

The bug report instructions are very clear

I added one more picture, which is actually a loading error in the MIDDLE of my building area (As you can see by the planks on the right). I'm staring straight down at a chunk that's supposed to be loaded.

@Black Hole

I re-ran buidltools, and placed the new server.jar on the different test environments. The problem is still occurring. I have updated the screenshot to the latest version, and have updated the versioning in the ticket.

You're using an outdated build. Please try to reproduce with the most recent one.

This looks like a more expanded version of SPIGOT-4764 and the very sparsely written SPIGOT-4763
