Ship teleported 120 sectors outside galaxy

[Deantwo]

found a fuel distress beacon. Berthed to the ship and noticed it's location.

And I assume that you got this message on either the Hail channel, which means the ship was in the solar system's scene but with corrupt coordinates. Or it was on the Friend channel, which is broadcast at super-sector range, but would still have to be in the solar system scene of a system in the super-sector.

In other words, exact same symptoms as the issues I linked above.
