[Freeciv-Dev] (PR#13194) Failed sanity check: punit->transported_by != -1

["Jason Short" <jdorje@xxxxxxxxxxxxxxxxxxxxx>]

It looks to me like something has caused the city to become landlocked.
 Sailing units trapped in the city are not bounced, and trigger the
assertion since they aren't allowed to "exist" at the tile.  The terrain
around the city is all forest, grassland, or desert.

Another possibility is that the sailing unit is erronously bounced into
the city.

For future debuggers:

(gdb) p punit->id
$30 = 2350
(gdb) p punit->tile->index
$31 = 633
(gdb) p punit->tile->city
$32 = (struct city *) 0x85a18d8
(gdb) p punit->tile->x
$33 = 9
(gdb) p punit->tile->y
$34 = 8
(gdb) p unit_types[punit->type].name
$35 = 0x8254da4 "Sail"
