Hi,
It should. here.next() should also work. Places are arranged in a
circular ring. here.next(i) is the same as calling here.next().next
()....next() (with i calls to next).
I'm guessing the problem might be that you are missing a finish. In
the snippet of code above, there isn't a finish, so the asyncs may be
running longer than you expected.
You might also try dropping the for loop down to 1..10 or something
small to try to see if that matters.
