cannot retrofit space port

[catweasel]

I upgraded the design of my large space port and when I wanted to retrofit the existing one, I noticed that the icon for it was gone. When ordering a retrofit from the construction yards screen, nothing happens. Any idea what is blocking the retrofit?

Not really. I guess you are not all broke?

Of course I'm not broke

Guess it must have been a glitch of some sort. I reloaded the game from the last autosave and the icons appeard again and so did the text message, that a retrofit was underway once I ordered it.
