Last night, after the Ion storm, I got back on and made my way to Freeport-5 in Omega-41.
After docking there (I'd just come from Coalition space, and screwed up when buying my new ship... forgot to remount my Medium Tractor and Adv Deep Scanner I guess) I withdrew money and bought those 2 items.
I then went in and bought 320 holds of engine part (At, I believe, $238 ea). When I went to undock, the game immediately disconnected from the server.
I tried this again, same thing... I thought it was my connection, but the third try I realized it was happening when I bought the engine parts. To test it, I tried buying less... not buying the scanner/tractor.
One time, right as it disco'd me, I saw white text that read "Something something Foster something something possible cheat" flash up... so it appeared SOMETHING about the engine parts was triggering some kind of cheat detection?
So, I tried just launching, and that worked. Then I tried buying the scanner/tractor and launching, that worked... so I just said screw the trade and left.
The only long-term issue (for a newb like me anyway) is that apparently every time I bought the scanner and tractor, it deducted the money from my account but did NOT keep the scanner/tractor... so I am out like 5.4 million credits... I guess I should have checked my balance... live and learn.
