when i tried to jump to Cortez->Manchester gate, i got lag and the scene was going until i got disconnected, when i entered again i was on the west edge of the system 54k way of the Manchester gate, then i saw other player ships passing at a very high speed when they start entering the system, i was very surprised, i though the ships where "teletransported" between the gates
It's not exactly a bug. It happens at every jump gate and hole. It'll pop you into a system, always at the same spot, before reverting you to the JG/JH you just went through. Losing connection or F1ing at a specific point in a system jump will leave you at that point. However, doing it on purpose is considered F1ing and is a violation of the rules.
