I have a question: I haven't played the game myself, but do any of these systems (including the automated docking mod) have the potential for failure, like in real life? It would be interesting if your docking program suddenly went haywire when you're closing in on a station!
In theory, no. However, the other day my RCS thrusters started misfiring for some reason and I had to take quick action to prevent a tumbling module from colliding with a solar panel array on my space station. I suspect that there might be a bug lurking in the docking code - or let's blame the deep space Kraken.
