The custom servers are supposed to continue persistently without crashing, and continue rolling over to allow people to vote on different factions/maps every time. Unfortunately this feature is rarely seen as the servers tend to crash at the end of one "game period" like clockwork. With more than 50-60 people on a server, it is fortunate to even get to the end of a game, let alone expect the server to get to this map/faction vote restart period. Sad!
