Server Crash whilst deleting a plot

[Hasenzahn1]

Server Implementation

Paper

Server Version

1.20.4

Describe the bug

When deleting a plot filled with Sculk Sensors and Trapdoors the Server crashes.(Gist file 1) After restarting the server and retrying the server the console is flooded with lots and lots of errors. (Found in the gist. File 2). The fps also drops below 2.

This is an error with Plotsquared and not with the normal paper implementation as it does not occur when removing the blocks with Worldedit (FAWE), or vanilla commands. It only occurs when deleting the plot with plotsquared. As far as I tested.

The size of the plot is not important. The error seemingly only occurs if the plot is deleted whilst a sculk Sensor is deactivating and updating the blocks near it

To Reproduce

1. Fill a layer of the plot with sculk sensors.
2. Place a layer of Trapdoors on top of it.
3. Add an Observer clock to always pulse on of the trapdoors. This sets up an chain reaction of opening and closing shulkers.
4. Delete the plot (/p delete)

Expected behaviour

The plot should be deleted without crashing the Server ;)

Using with sculk_sensor or calibrated_sculk_sensor.

Replicating is not that easy. It requires a certain size.

Hi,

I can't reproduce the issue with the latest PS and Paper versions. Also, in the log files you provided, there is no log entry referring to PlotSquared. Please let me know if the bug still persists for you.
