Player reports it doesn't crash single player.

So perhaps a sidedness issue. The new 4 sides sidedness is tripping up most mods.

I cannot reproduce this. I placed down a Snowman Companion with a bow as a weapon and the server did not crash. Same thing happened when placing it down near an enemy - the Snowman Companion attacks the enemy and the server doesn't crash.

Closing as I cannot reproduce this and there hasn't been another reply by you. If you open issues, please do not ghost them and actually try to help with the resolution (I've had this 'no reply'-thing happen with you twice already). Please reopen this issue if you have more information.
