Arc-Tek Cryo Guard: Drone Aggro doesn't proc dreadnoughts

Tried gapping the dreads so they would fly into the dreads, tried getting right on top of them, and nothing would get the drones to actually tightly circle the dreads like the Aggro Chip upgrade is supposed to do.

Confirming. Seems Elites cause the same problem, in my experience.
There is a "workaround" that's not really practical, but if you're able to get the Dreadnought/Elite totally out of range of your drones' patrol radius, AND have nothing else in the radius too, they will SOMETIMES fix themselves and properly attack things again. Until they reload, and then the bug it can happen again.

Makes doing the Weapon Mastery for these an utter chore of a coin flip. They're just not good enough patrolling you, but they're also so unreliable with Aggro Chip.
This can also happen with Thunderbird Drones if you take Aggro Chip, but they at least have a large radius of effect so it's much less of an issue.
