Have several issues.
Issue 1: when you (try to) order slaves to attack a neutral or enemy drone, they do guard.

Issue 2: when you tell drones to attack a particular target, they usually ignore that target and kill it last. Rarely does target override to attack a specific enemy actually work.

I think there are others out there, other people would know better so I hope they'll post here as well.

Base RTS controls were bugged last time SBP attacked TFC, not sure if it was ever fixed.
