For folks who may not have heard this before:
The AvA does not reset if one side captures all the other side's bases. Instead, the arena becomes unuseable. This is not something that can be fixed under present circumstances. Once the arena is porked, it stays porked until a staffer becomes available to come in and set it all up again. On a smaller map, such as Okinawa, this can become a significant problem.
So: Please do not try to take all of the other side's bases. You can take SOME of them, that's fine! Just not all of them, please.
