Mobs attacking each other?

Seems since Issue 12, any mobs guarding a hostage will frequently regard other mobs around them (even if same faction) as hostile and will attack them if they're too close. One example of this is during Marshal Brass' mission Recover Amanda Vines, with the shivans guarding her attacking other shivans (because they spawned too close).

Has anyone else noticed this?

nope

Actually, I have noticed this from time to time. It seems kinda rare, but occasionally I've seen Longbow shooting each other in missions, there was one time an end mob looked to have shot itself up, boss included, and, more frequently, the Arachnos on the GW mission of Seer Marionios arc (although that one I think is scripted)

Yes, I've noticed this. Appears to be mostly ambush spawns incorectly flagged as hostile. Has been around for a while.
