How do you make this verb delete the old one and create a new one?
turf
City
icon = 'city.dmi'
density = 1
verb
City_claim()
set src in oview(1)
usr.City += 1
usr << "[usr], you conquered a city!"
usr.Population += 100
usr.City()
src.Owner = "[usr]"
del(src)

BTW, I wnat it to respawn in a random location.
