Observed behaviour

I was exploring one of Alex's Caves and a boss spawned that instantly crashed my game with an error saying "failed to render entity".

The game crashed whilst rendering entity in world
Error: java.lang.NullPointerException: Cannot read field "f_267362_" because "entity" is null

Expected behaviour

My game to not crash
