Was flying a ship on a server. Suddenly, I was hit with the "Ship overheating" message. No damage to ship blocks whatsoever, no damage to ship HP. Ship did *not* kick me out of the core initially, despite the sudden overheat.
Ship inaccessible. Reboot dialogue works, returns a "30 second" reboot time. Reboot will reset HP if one intentionally damages the ship afterwards, but it will not stop the ship's overheat timer. Both players in-sector showed the ship as overheating, however, when an admin came to investigate, their client did *not* show it as overheating.
Uncertain if it's possible to reproduce this intentionally. Cause also uncertain.
Image of overheat timer below. Note that damaged HP was intentional, in an attempt to determine whether causing ship damage would make it possible to reboot successfully.
