Griefers have spawned these floating entities in my server (Ender Dragon and fire charges) that I cannot interact with. They are causing serious lag, due to the ender dragon having a huge name of random characters.
How can I delete these entities without having to resort to deleting the entire world?
This is a Minecraft Java Edition server running Paper/Spigot.
The dragon doesn't seem to really exist as a living entity and is immune to /butcher.
