I've noticed that I can create an arena, set it up the way I like it, fly awhile, then exit and go completely offline. If I come back a few minutes later, my arena is still available and still set up the way I left it, even if nobody else has been flying there during the interim.
Question: How long will my arena "live" in that condition? What are the variables determining the lifetime of an arena that's empty like that? Will it stay alive longer after the creator leaves if others remain flying there?
???
