Specialist teleported outside of map (stuck)

[Imperfect Cog]

I was killing the 3 groups of enemy soldiers for the quest 'beyond tomorrow' and one of my specialists teleported outside of the map on the other side of the map and is now stuck. Is there a way to kill or delete said specialist to free up the slot it is taking up?

I was attacking a beast on the world map and my specialist was "teleported" to the exact same location. Haven't been able to solve it.
