I spent this afternoon beelining back to the bubble from 8,500ly away. Think it was about 30 jumps to go when this showed up. FSS confirmed rogue signal sources in that direction. Do we think it's intentional that the Stargoids can project their visible images at superluminal speeds? My guess is they've been dropped in as stars, but the game engine has no actual concept of the speed of light.
Weirdly I lost track of them as I got closer. Skybox rendering may have some oddities.
