Server Implementation

Spigot

Server Version

1.21.4

Describe the bug

When running /duels arenaregen create on Spigot 1.21.4, FAWE throws a ClassCastException in PaperweightPlatformAdapter.getEntities() while Arena Regen is attempting to save a schematic.

It appears FAWE is still trying to cast net.minecraft.world.level.entity.EntityTickList to net.minecraft.world.level.entity.PersistentEntitySectionManager, but in 1.21.x these are no longer compatible types due to changes in Mojang’s internal entity management.

This crash occurs before Arena Regen can finish saving the arena schematic and happens 100% of the time when the command is run.

Though i think the issue might be from an outside source but for now i can only see this error coming from FAWE.

I've also made a support ticket to the developers of the Duels plugin i am using but i am just talking to a brick wall. For the past 3 days none of them have replied to me despite seeing the ticket

To Reproduce

Run a Spigot 1.21.4 server.

Install the following plugins:

FastAsyncWorldEdit 2.13.2-SNAPSHOT build 1160

Duels Optimised 4.2

Arena Regen 6.30 (Duels extension)

Join the server as a player.

Run the command:

/duels arenaregen create (name)
Observe the server console — a ClassCastException occurs and the command fails.

Expected behaviour

Expected to just create the Arena Regen by making the schematic ti used to work before something happened. Problem is that i don't know what exactly happened to cause this
