- ChunkUnloadEvent

Version:
This server is running CraftBukkit version dev-Spigot-146439e-3f8e416 (MC: 1.21) (Implementing API version 1.21-R0.1-SNAPSHOT)
Guidelines Read:
Yes

A plugin tries to update a block during the ChunkUnloadEvent, before the chunk gets unloaded.

In previous versions this worked fine (tested with Spigot for MC 1.20.6): The event was called before the server actually considers the chunk as unloaded, allowing plugins to still process the chunk during the event before the chunk is actually moved to the unloaded state. In 1.21 (even with the recent bug fix related to chunk unloads included: https://hub.spigotmc.org/stash/projects/SPIGOT/repos/craftbukkit/commits/f5a63f7345eaf167d2664dc04f4e2cf7458c26fc), the following error is observed:

Edit: Maybe caused by: Seems like there is a new check in GenerationChunkHolder.scheduleChunkGenerationTask -> isStatusDisallowed which is already reduced in ChunkMapDistance.runAllUpdates based on the new ticket level (updateHighestAllowedStatus), before the unload callback is handled (updateFutures).
