And it was not an exception.
In the below screen Zakdorn has constructed the Subspace Analyser and even a scan from the colonized/assimilated system does not work in the map border row.
I have just tested it by scrapping such building myself.That's one of the parts where it's not complete yet, yes.
But don't those TRs get removed in the turn after the building gets destroyed? (Not the current turn, the next one)
