Multiverse-Core issues (not working)

[deinemuttermitbutter]

Hi!
So im trying to run a fabric server on 1.20.1 with the Cardboard mod installed.

• On startup: Multiverse-Core CAN load the default world

issues: on world creation, world import, /mv load and so on....

• Multiverse-Core is running and working for commands like /mv list

/mv create test normal

[22:46:20]` [Server thread/INFO]: --- issued server command: /mv create test normal Jan 08, 2025 10:46:20 PM com.onarandombox.MultiverseCore.utils.CoreLogging$InterceptedLogger _log INFO: [Multiverse-Core] Loading World & Settings - 'test' - Env: NORMAL - Type: NORMAL [22:46:20] [Server thread/INFO]: [STDOUT]: Bukkit#createWorld 0 Jan 08, 2025 10:46:20 PM com.onarandombox.MultiverseCore.utils.CoreLogging$InterceptedLogger _log SEVERE: [Multiverse-Core] The world 'test' could NOT be loaded because the server didn't like it! Jan 08, 2025 10:46:20 PM com.onarandombox.MultiverseCore.utils.CoreLogging$InterceptedLogger _log SEVERE: [Multiverse-Core] We don't really know why this is. Contact the developer of your server software!

so the issue lays here: The world 'test' could NOT be loaded because the server didn't like it!

/mv reload

WARNING: [Multiverse-Core] Exception while loading value for environment

so are both permission issues ?
