That's what I thought
The only thing I guess it could be is:
# Set this to lowest, if you want Multiverse to handle the respawning.
# Set this to high, if you want EssentialsSpawn to handle the respawning.
# Set this to highest, if you want to force EssentialsSpawn to handle the respawning.
respawn-listener-priority: high
I'm quite sure that's the default though, and I don't have Multiverse installed.
