[Freeciv-Dev] (PR#4785) disappearing archers

["Jason Short" <jdorje@xxxxxxxxxxxxxxxxxxxxx>]

I walked up with a settlers next to an enemy's cannon.  So I brought up 
the bodyguard: two units of archers.  Things now looked like:

     CA
    AS

and I had no MP left.  So I set both units of archers on "goto" toward 
the cannon, to see if I could attack first (which sometimes happens 
since the end-of-turn order is buggy).

At the end of the turn I got the message "Settlers lost to an attack by 
xxx's cannon near yyy".  And both units of archers were just gone. 
There was no message, and no legitimate reason I can tell for their 
disappearance (their homecity wasn't conquered or anything like that).

Not reproducable.
