Gate gun mechanics in corruption 5 lowsec is bugged, and has been since Havoc, and is regularly causing NPC player kills that GMs refuse to reimburse
Bug in action: https://youtu.be/7I2Xjq1WJMY
Basically, they behave correctly until a ship with a criminal timer cloaks and then decloaks on grid with the sentry guns. Then the guns go active and kill anyone with a criminal timer
EBR-42341 (from the client who cloaked with an active criminal timer, and then decloaked triggering the bug)
EBR-42342 (from the client who wasn’t evr cloaky but got gate gun aggros after the cloaky ship trigged the bug and then left grid)
