Expected behavior

The server was not supposed to shut down.

Steps/models to reproduce

I typed /cave go and the server crashed. It's not always the case.

BentoBox version

Plugin list

No response

Other

No response

[tastybento]

It looks like an incompatibility with pufferfish-1.18.1.jar. Do you see the same error with Paper?

[myavuzokumus]

I've only had this problem once. I thought maybe it was a rare bug that triggered an issue. If there is no problem on the plugin side, the issue can be closed.

NoClassDefFoundError error should be thrown only if there already exists some error before. At least that is how I understand that exception.

I had a similar problem:
