Hello!

This is a bit of a weird one. I havent been able to reproduce the issue myself, but the server has crashed 3 times now for the below reason: https://mclo.gs/3jYEUqp

It seems to be linked to a specific dragon causing the crash each time ( we have had two different dragons cause the crash)

Both dragons were not being used.

This was fixed with #185, and a release containing the fix will be out soon.
