Ah the controlling faction change idea would make sense.
I tried to just check if I could see anything in the system map, and something absolutely bizarre happened:
I'm in a hauler, I just fitted for some long distance flight, when I read your answers, so I open galaxy map, pick the system and push the button to go into system view. Next thing I know, I have a station interface infront of me, but not only that, I'm clearly in a (my?) Vulture's cockpit - as I puzzle about what just happened, the game crashes...
Edit: there was another funky thing going on in that system's other station... It was unusually crowded with ships, but they were all just flying circles (not talking about the security ships). So I get docking permission, set my speed to zero to let the docking computer take over. and then it sits... and sits... waiting in queue... at 5 minutes left, I turned off the docking computer and then turned it back on. back into the queue until finally, the landing permit expires!
Not a single ship went past me to land in the entire time.
So, well for the first time, I had no choice to land my Anaconda manually

I was avoiding it, cause flying out of the coin slot, you get a weird ground effect-like buoyancy, making you float upward to actually scrape the ceiling of the coin slot, unless you hit lateral thrusters to compensate at the right time.
So when I flew in, there was no such effect though, went totally straight without any updraft. Same thing for the second time, no problem at all. (no, the "buoyancy" is not from bumping the bottom of the ship and getting sent up, that's not it. Not touching anything for this to happen when coming out. It only happens in one direction.
