Mobs not attacking even when attacked.

[Wavicle]

This was in a Skulls mission around level 15 or so. I'm sorry I didn't take careful note of which mission. It was NOT either Stockwell or Eagle Eye. May have been a radio mission, or perhaps a mission from an OG contact.

We killed the named boss and similar to some missions (from Stockwell for example) most of the enemies remaining turned and fled. However SOME of them simply returned to their spawn points and stood there.

 

THEY DID NOT BECOME UNTARGETABLE. We were able to continue defeating them FOR REWARDS without them reacting at all.
