I don't know if this is a known thing or not, but I found this relay station that is not marked on the system map. Warning: I arrived half inside the thing and lost shields 40% hull as a result :/ [screenshot button isn't working for some reason to had to resort to the snipping tool..sorry about that]. I have to go to work now so can't investigate further so thought I'd post here just in case it *is* a new something
