Well, this was first time ever in encountered this bug: After a road trip from Ontario system, i docked in Waterloo Station - New London. I tried speed-docking and after message appear, game crashed. I restarted the game, but instead to be next to Waterloo Station, at least, i was back in Ontario, like i never left from there. All load of the ship was in same place (nanos, CM etc so the ship was not destroyed).
Sometimes it happen to me also, dont know why, it's just annoying that the effort of your travel from point A to B will just waste. But the good thing is,your cargo is still in your ship.
It's actually not a bug, but rather an anticheat feature which happens to be prone to occasional false positives.
There are a few "oldschool" methods of cheating this particular method effectively counters, but it might also get confused in cases like lagging out or the game crashing right when you attempt to dock, and what happened to you happens when the anticheat mistakes that for one of those cheating methods.
Believe me, that is not as bad until you dock at the station with full cargo of ores, only to crash and reload back to the starting point with empty cargo hold.
