Hilarious AI - zombie zealots

I fast travelled to my outpost on Zamka to be greeted by 10 lvl 14 Varuun Zealots just standing around in sleep mode.

I repaired the damaged harvester, turret, solar array before engaging.

What gives, why is the AI so….sleepy. The aggro distance is super close.

If I hadn’t started shooting, I could have just left them standing after the base repair.
