Chunks can get randomly reverted

Server Implementation

Paper

Server Version

1.20.4

Describe the bug

Using the PlotSquared full world feature, chunks can get reverted randomly when unloading/loading. This does not happen in normal worlds that PlotSquared isn't controlling, only in worlds that PlotSquared controls. Both videos are done on the same server with the same plugins and config, just using either a PlotSquared controlled world or default world - which is why I am raising here instead of FAWE issues.

To Reproduce

1. Create a server with PlotSquared config world: true
2. Login to the server, run /p auto to create a fresh world
3. Load a large schem and paste it
4. Fly about, loading and unloading chunks, random chunks will get reverted as shown in the video named PlotSquared world chunk issue

Expected behaviour

Chunks should not be reverted
