...A Long time ago, a band of gun happy allies went and killed a "Doom-Brick" on old EE server; but the ship overheated before we could salvage any part of it. This has been around since the shields were doubled, a short while after the GUI Patch yet well before rails and shipyards.
Now, I have acquired a Blueprint that overheats after this 60 seconds, backed up by a friend who also noticed this behaviour after using it as a target-dummy for weapons fire.
This may cause a stir since it is a Vaygr blueprint. But its exhibiting an as-of-yet unknown (At least to me, hence reporting) Bug/Exploit that denies salvage of the vessel. There may be other hidden issues with the vessel as well.
