5.6.3: If multiple entities have this effect applied, other entities will now target the nearest entity with this effect.
11.1.5: Revised functionality in an undocumented change in v11. Entities are now pinged to target on first effect application and every 200th world tick.
11.1.6: Improved performance for Universal Hatred and Insanity Mode (Universal Hatred, instead of looping all entities on effect application, then looping through all entities again to target, will instead use a global boolean flag alongside the world tick checker. The same has also been added to Insanity Mode which "pings" all hostile mobs immediately on player join)
