At the early stage of my campaign, I sent Anakin to Abregado-Rea, but while he was on his way, I got an event that resulted in his defeat. Much later in the campaign (week 57), I rescued him from a CIS planet, but now I can’t send him there. When I drag him onto Abregado-Rea, nothing happens.

Is there a way to fix this without basically restarting my run?
