We will need a little bit more info to help diagnose the issue:

1. Do you have MultiverseCore installed as a plugin on your server?
2. What is the MultiverseCore version and build number

no i dont use multiverse

config settings:
multiverseEnabled: false
safeTeleport: false

I just want to double check where you are setting those values:
Are you using the old big config.yml, or are you using the new seperate "core.yml"?

If you still have the old big config.yml then you should remove it, and instead use the new separate configs.

i use the core.yml build b642

this happens when loading the plugin on server start: https://hastebin.com/ujiyuhujif.vbs
i can confirm this happens to me and i don't use multiverse too and i'm running build 642

thank you

sorifiend, can you do something?

Yes the teleport function works.

Does the plugin still function and do a successful teleport? If so then I can maybe hide the error otherwise it will take a lot more digging (I couldn't work it out last time I looked).
