Hello @Foxed
about camping Supergates: yes, allowed. It’s part of the risk. Only the normal K-warping counts towards our “No camping warp rule”.
I can verify your story though and restored the SV on ECC at coordinates 0 100 0. Make sure to pick it up after you ran the Combat Mission.
Keep in mind for the future that it could be that you just used the Supergate wrong and your friend was in the Cockpit and you only in the passenger seat!
And if you read the Guide then you should NEVER use the Supergate as Passenger or it happens what happened to you.
ONLY the pilot should use the Supergate.
