On the server I'm running, I have had the Jump and survey module cause users to get kicked after using them and then selling them. After selling them, it kicks the user upon launch. In the logs it says Possible cheating detected: Username (Ship relatede)
Docking modules did the same thing when I was testing them. Kicked me serveral time off my own server.
Just wanted to let you guys know. I assume these things are still works in progress. As such I've removed them from sale stock.
