Hello, my game crashed randomly on my server. Every time I tried to reconnect I got the same error:

java.lang.NullPointerException: Cannot invoke "java.lang.Boolean.booleanValue()" because the return value of "java.util.Map.get(Object)" is null

Removing the mod helped and I was able to join the server.

Thank you for reporting this. This should be a simple fix, and I’ll get to updating as fast as I can.

Fixed as of version 1.0.1, which has been released.

Thank you 😊
Maybe you want to create other particle mobs, like butterflies etc.
Greetings.
