Expected behaviour:

No errors at start-up / initialization.

Steps to reproduce:

Start server.

Purpur can be found here. https://ci.pl3x.net/job/Purpur/ https://github.com/pl3xgaming/Purpur

I am also using ViaVersion and all relevant dependencies for that as well (latest dev/abstract builds) but I do not believe it to be the cause.

Purpur added their own world configuration, which I wasn't mocking when loading entity type data from the server. Quick testing appears to fix this now: https://github.com/bergerhealer/BKCommonLib/commit/047be88ffdc26e9f118aba770e104b36ae3e0d8e
