On a public server, this is being fired every other second, according to the owner.

Looking at the source code suggests that when the task is being instantiated the LivingEntity is not valid, so it doesn't set 'target' to be that entity. However, it's still called, meaning that it's trying to call a null variable.

Was about to create a ticket for this until I stumbled upon this report. Been seeing the NPE all over the place in my console with dev build 2199. :)
