Some chunks don't generate and terrain is not planes biome anymore

Server Implementation

Paper

Server Version

1.20.1

Describe the bug

Chunks failed to generate while flying, and the biomes seem to be taken from the seed not fixed to Planes. Console did not produce any errors or warnings, with PS debug config set to true.

To Reproduce

No exact reproduction steps. Seemed to happen out of nowhere.

Expected behaviour

After updating from v6 to v7 on a 1.20.1 server. Sometimes chunks would not generate in random areas. This only happened once and couldn't replicate it after trying.

Server was struggling to generate chunks while sitting at 200%, with high RAM usage.

PlotSquared Version

PlotSquared version 7.0.0-RC.1-Premium

Checklist

• [X] I have included a Plot debugpaste.
• [X] I am using the newest build from https://www.spigotmc.org/resources/77506/ and the issue still persists.

Anything else?

Unable to verify if still happens on RC.2 because it's not easily reproduced

@MrJoshuaT Have you tried without Multiverse? Also I am not sure if that produces lag: [09:51:15] [Server thread/WARN]: Ignored advancement 'minecraft:recipes/decorations/black_carpet_from_white_carpet' in progress file ./plots_128/advancements/ce8128d0-83e8-4491-be45-f8241aa46fa5.json - it doesn't exist anymore? And then this: [09:51:15] [Server thread/ERROR]: Tried to load unrecognized recipe: minecraft:red_wool removed now. Looks suspicious to me, never saw anything like that before. Might be a worldgeneration issue

@OneLiteFeather I've always run PlotSquared with Multiverse so I wouldn't think that would be an issue. To isolate that I'd need to setup a separate server to test that.

Also that advancement and recipe messages are weird I agree, but every server I've upgraded from 1.19 to 1.20.1 have produced this on first login. Also those messages appeared way before flying around so I wouldn't think those would be related

PlotSquared version 7.0.0-Premium will try updating PlotSquared and see if it happens again
