I seem to get thrown into the wiring overlay when I cross 400 refined metal for when I only have 1 refined metal type and all research unlocked.
It happened to me a bunch of times in succession as I was building out some conductive wiring using the rock crusher to produce refined iron. But couldn't pin what it was. But it happened again when I was waiting for enough refined metal to build a exoforge.
Didn't see another bug on the matter.
As per description.
