Server crashed again right after restarting from that,

had to disable the mob from the config in order for the world to be playable again.

Previously I had already seen those mobs spawn around with no issues (just by exploring around in spectator mode) but it was until now that I've seen it fight something.
It's a shame that I had to disable such an interesting mob.

OK, I need to just chek to make sure it is an EntityLiving before running that code -- I think that should fix it.

This should be fixed out ... the magic missile should now be set dead without trying to affect things that are not valid living entities.
