2nd save, I astrogated to the claim beacon (I might have visited a Big Lidar Contact before that I don't remember), a derelict Cothon spawned in and I made my way to it. The EVA failed (reactor busted), so I turned on my ARM to grab it and moved to the OMS to turn off my front thrusters and prepare for astrogation back to Ency. Then I heard zapping and lost power. The Cothon seemed to have revived and was attacking me, I panicked and turned on my weapons and shot at it til it stopped moving and the IFF automactically set the derelict back to neutral.
(I also got a trojan warning after zipping up the log folder from Windows Defender please be careful)
