Project 1999 - NPC Spawn Issue: Cracktusk has zone wide aggro

I read the post on the Cracktusk wiki page and it seems this zone wide aggro bug is back after yesterday's patch.

How to reproduce:
1. On red server, I was camped near Splitpaw entrance.
2. I logged in this morning and killed a Gnoll. No biggie.
3. After the epic battle, an elephant mob appeared on the horizon racing towards me.
4. The elephant mob, lets call him Cracktusk, gazed on me with the frenzied anger of someone who had taken his mother out for Chinese food and never called her back.
5. I snared and rooted Cracktusk and ran north to the bridge zone line.
6. I waited at the zone line for Cracktusk to catch up.
7. I zoned to NK, cast camo on myself, and returned to SK.
8. Cracktusk was slowly heading away from the zone line, no doubt seething with the rage of a thousand bumblebees.
9. When Cracktusk was out of range of any spell or bow (he was almost to the first ridge, clearly out of typical aggro range), I dropped camo.
10. Cracktusk IMMEDIATELY renewed his unholy anger and swore to end my house and all who serve me.

Working as intended?
