Easiest fix ever; house rule it.
There's so much internal conflict on drones in Catalyst it's not even funny; Rigger 5 left out Armorer autosofts by design (confirmed by one of the writers, as they felt drones couldn't be trusted making ammo and the like), but Hard Targets included them not only in the form of an autosoft but an entire reloading drone. Repair costs have been changed three or four times. Armor values are all over the place, and drones are for the most part as durable as paper maché in a rainstorm. Modified stat lines did or did not make it into Rigger 5.0 (again, according to one of the writers). We still don't have a clear answer on which attributes to use when rigged in (some skills use mental instead of physical, some remain physical). And by RAW a micro-drone, which can be the size of a literal insect, is only a moderately more difficult to spot than one the size of a bear; the fact that they have miniscule dice pools unless you spend tens of thousands of nuyen on something that can be completely and utterly destroyed by a heavy pistol doesn't exactly help.
TL;DR, just house rule it. And if you're playing missions; don't play a rigger.
