Flying around

To Reproduce

1. I was just flying around existing chunks. It seems that when it tries to spawn or load a goose, it crashes the server. And the server will crash if I spam throw the goose egg. This message appears at crash, and it will also appear if I use the "spawn goose" egg, although not crash.

Additional context
This doesn't seem to happen with any other mob. They all spawn fine.

Closing due to inactivity and no further information that implies anything other than coremod interference.

Can you include your full game log prior to the crash? This is lacking information in the log.

I am led to believe you have some sort of coremod that is interfering with the mod and causing this issue
