Likewise. This article caught my eye, because it describes a phenomenon similar to one I've observed locally over the past year. I'd be curious about how well this meshes with what you've seen.
We have a fleet of (at least) 30 drones operating in a similar manner over Indiana. All of them reliably following paths between fixed waypoints. Upon reaching their waypoints, they tend to loiter place for a bit, change elevation, then move to the next point on their route. They typically come out around 7 pm, and disappear around 5 in the morning. They never fly in poor weather conditions.
The bulk of them seem to be Delta-wing aircraft, with lights at each point of their triangular bodies, and another array of three white, rectangular lights beneath them which will often flash, be disabled, or even on in lieu of the lights at their wingtips. I've estimated them to be between 6 and 15ft in wingspan.
They have a forward-swept vertical control surface with a red light at its apex, that I've variably seen at the top, and the bottom of the craft.
I've seen them fly forwards, backwards, and taxi side to side in rotating triangular formations of four, with one at the epicenter. They typically fly around 50mph.
They first appeared in the large numbers around south-central indiana July of 2018, but operate at lower densities across much of the southern half of the state.
I've always attributed it to the nearby naval warfare research center, due to the lack of public comment on the part of our local government, or regulatory bodies.

I'd be interested in more details (either here or via e-mail to my username at gmail) as to where you've seen these flying. I'm basically in between Bloomington and Crane (which is, I assume, where you're referring to) and have several friends who work at various levels in law enforcement in the area and even more friends who work at Crane.
This is the first I've heard of anything like this in the area, though.
