Getting an error when leaving the server, which eventually crashed my server.

[danekoenders]

Describe the issue

Every time a player leaves it gives me the error listed below. After some time, the error will make the server not joinable anymore. So it will stay online, but doesn't let anyone in. Because it will keep loading and loading, but eventually kick your with exception null.
